Photonics Industry

Joanna Cherry Excerpts

[Carol Monaghan (Glasgow North West) (SNP)]

I beg to move,

That this House has considered the photonics industry.

It is a pleasure to serve under your chairmanship, Mr Flello.

The usual reaction to any comment about photonics is, “What’s photonics?” It is worth pointing out that photonics is nothing to do with fold-down sofas and that it is not the study of protons. Photonics comes from the word “photon” and is the science of light.

Scotland has a great tradition in science, with figures such as Lord Kelvin, James Watt and Thomas Graham featuring strongly. The most famous physicist in the photonics field, although he is probably much less well-known than those other figures, is James Clerk Maxwell. Maxwell was born in Edinburgh in 1831 and brought up in rural Kirkcudbright, before moving back to study at Edinburgh University. A brilliant mathematician and physicist, he moved to Cambridge at the age of 19. On arrival, he was given a list of rules and told that the 6 am Sunday church service was mandatory. Reportedly, Maxwell paused before replying, “Aye, I think I can stay up that late.”

Maxwell’s most notable work was formulating the classical theory of electromagnetism, which for the first time brought together electricity, magnetism and light. His development of the Maxwell equations, which describe a wave as having an electric and magnetic component, are fundamental when describing the propagation of light. Many argue that Maxwell’s contribution to physics is on a par with those of Newton or Einstein. Indeed, Einstein himself said:

“The special theory of relativity owes its origins to Maxwell’s equations of the electromagnetic field.”

Those equations changed the world forever and are the bedrock of photonics. In recognition, 2015 was designated the international year of light, to celebrate the 150th anniversary of Maxwell’s electromagnetic theory of light, thus marking his contribution as the father of photonics.

I knew none of that when I was considering university courses. I chose my course—laser physics and optoelectronics—because I enjoyed physics and, frankly, because the name sounded impressive. As a 17-year-old, I had no idea that Strathclyde University was one of the UK’s leading institutions for photonics. I want to make special mention of Professor Robbie Stewart, whose enthusiasm for and expertise in photonics was matched by his burning desire to see every young person—even those who were sometimes reluctant students, such as myself—achieve success in physics.

[Joanna Cherry (Edinburgh South West) (SNP)]

My hon. Friend is making a very interesting speech, although I suspect that she will be too modest to say that she has a PhD in photonics—

[Carol Monaghan]

It is not a PhD.

[Joanna Cherry]

Well, a postgraduate qualification in photonics.

My hon. Friend mentioned Strathclyde University. She will also be aware that Heriot-Watt University, which is in my constituency, is a centre for the study of photonics and quantum science. I have been very privileged to meet Professor Duncan Hand and other researchers and staff there, who showed me that photonics applies in a variety of practical fields, including cyber-security, cancer treatment and the protection of civilians in war zones.

[Carol Monaghan]

I thank my hon. Friend for her intervention, and I will talk later about some of the applications of photonics. As she suggests, the central belt of Scotland is a hotbed for photonics, from Glasgow and Strathclyde in the west to Heriot-Watt and Edinburgh in the east.

[Carol Monaghan]

Brexit is one of the biggest challenges that the photonics industry faces just now, and we need some clear answers about how the industry will be supported through the Brexit process. I will come back to that point later in my speech.

The strength of the Scottish photonics industry is underlined by the fact that when the UK Government invited the Fraunhofer Society of Germany—Europe’s largest research and development provider—to work with the UK, the first centre was established in photonics and was in Scotland at the University of Strathclyde. Of course, photonics features in every part of the UK and there are other major photonics clusters around the UK—Southampton also has a high photonics concentration.

I will give some facts and figures about the UK photonics industry. It is a growth sector, with 1,500 companies employing more than 70,000 people. Its economic impact is impressive, with a sustained growth of 6% to 8% per year over the last three decades, and an annual output of £10.5 billion. That is comparable to the pharmaceutical industry, but of course photonics is far less well-known, partly due to a lack of public understanding, but also to the industry’s high number of businesses, including SMEs. In order to give the industry a voice, the Photonics Leadership Group was set up, with John Lincoln at the helm, and I was delighted that he was able to be present at the inaugural meeting of the all-party group on photonics in October.

A key point about the photonics industry is that it enables other industries to be competitive, with 10% of overall UK jobs depending on it. Photonics is a key enabling technology, encompassing everything from lasers and cameras to lighting and touch screen displays. Photonics is also critical to increasing manufacturing productivity, delivering efficient healthcare, and keeping us digitally connected and secure.

The range and depth of the photonics field is vast, but I will highlight a couple of examples. The first is sensing systems in autonomous vehicles. Those cars navigate using radar, lasers and cameras linked to a computer. A horizontal laser can send out pulses, and by measuring the time taken for the pulse to return, the distance to obstacles can be established, in much the same way as bats use echolocation, so the cars can detect hazards and slow or halt as appropriate.

Lighting and displays are one of the most visible expressions of photonics as an enabling technology. Light emitting diode—LED—lighting is progressively replacing traditional fluorescent bulbs and is finding its way into new areas including signage, illumination, consumer electronics and even clothing. LED technology is projected to become the dominant lighting technology before the end of the decade. By 2020, more than 95% of lighting turnover will be based on the technology.

Another area where photonics has been revolutionary is in the detection of counterfeit goods, which are estimated to cost businesses £3.5 billion per annum. A technique has been developed by the National Physical Laboratory in Teddington to determine whether items of clothing are fake. The technology involves terahertz radiation. When a fabric sample is placed within the beam, the composition and structure can be ascertained, as different types of materials give rise to varying rates of scattering and absorption. The fabric’s unique signature will indicate whether it is genuine or a clever copy.

In healthcare, we are all aware of laser eye surgery and endoscopy technologies, but the photonics impact in that area is massive. A new technology known as photodynamic therapy, or PDT, uses light-activated drugs to kill cancerous cells. Plasters embedded with LEDs developed by the Scottish firm Ambicare Health are being used to treat skin cancer in combination with light-sensitive drugs. PDT is simple to operate and portable, meaning that patients can go about their daily routine while receiving it.

The timing of this debate is particularly useful, coming off the back of Monday’s industrial strategy Green Paper. While the 10 pillars of the strategy have the potential to support the continued development of photonics, the vital role of enabling technologies, such as photonics, needs to be fully recognised. They provide the competitive edge in product performance and manufacturing.

[Joanna Cherry]

My hon. Friend has spoken much about entrepreneurship and SMEs in the area of photonics. Does she agree that universities such as Heriot-Watt in my constituency are important engines in entrepreneurship and innovation in photonics? For example, in the past five years alone, three spin-off companies have come out of the institute at Heriot-Watt.

[Carol Monaghan]

I thank my hon. and learned Friend for her intervention. What we see with a lot of these industry-facing universities is great and rich partnerships between industry and research that allow SMEs to flourish.

Less than 5% of the value of high-technology goods, from mobile phones to aircraft, is in the final assembly. Most value is in the design, the critical components, which are often photonics such as cameras, screens, sensors, and the manufacturing equipment, which is also often photonics, such as laser marking or cutting. Manufacturing strategy must therefore be refined to ensure support for the research, design, development and manufacture of the hidden technologies that will secure a productive future. The UK has globally leading photonics research and a strong export-driven photonics industry, but as a global industry, photonics is sensitive to changes in international trade. Care is needed to ensure we continue to develop and manufacture this enabling technology in the UK.

As with many other industries, the shortage in science, technology, engineering and maths skills poses a threat to the photonics industry. Those shortages are well recognised, but still they persist. Difficulties in the recruitment and retention of STEM teachers only add to the problem. What practical steps are the Government taking to address those shortages? What role does the Minister see enabling technologies taking in the industrial strategy?

The biggest concern for the photonics industry, as has already been mentioned, is Brexit. Access to the single market and to skilled and experienced staff is vital to many photonics companies. With the Government driving on towards an increasingly hard Brexit, what steps are being taken to ensure that this key part of the economy is secure? Why is there no chief scientific adviser in the Department for Exiting the European Union? Photonics is one of the key industries for the future. I encourage all Members to find out how photonics affects their lives and how photonics is on a path to making the 21st century the century of the photon.

[The Minister for Universities, Science, Research and Innovation (Joseph Johnson)]

I start by thanking fellow Members, including the hon. and learned Member for Edinburgh South West (Joanna Cherry), and the hon. Members for Glasgow North (Patrick Grady) and for Strangford (Jim Shannon), for their passion for this under-appreciated sector. In particular, I thank the hon. Member for Glasgow North West (Carol Monaghan) for calling the debate. As she mentioned, it is particularly timely, given the launch of the Government’s industrial strategy Green Paper by the Prime Minister earlier this week. I congratulate her on her initiative in setting up the first all-party group on this exciting sector.

Too often, the photonics sector is unfairly and unwisely overlooked. We have heard this morning that it is a fascinating field and a great example of the types of sector that we are focusing on in our industrial strategy. It also makes a great and tangible contribution to all parts of the United Kingdom, including Scotland and Northern Ireland. As an enabling technology, it underpins a wide range of sectors and applications, including aerospace, eye surgery, LED lighting, counterfeit detecting and all the other important examples that the hon. Lady gave. There are more than 1,500 photonics manufacturing companies in the UK, together employing more than 70,000 people. They generate an economic output of £10.5 billion. Our industrial strategy looks to build on that kind of success, further strengthening our science and research base while helping to bring new goods and services to the market more simply and more rapidly.

The photonics industry has been built on the UK’s outstanding expertise. The hon. and learned Member for Edinburgh South West mentioned that it was particularly evident in industry-facing institutions such as Heriot-Watt. The Engineering and Physical Sciences Research Council maintains a significant portfolio of photonics research spanning across multiple themes such as ICT, physical sciences and manufacturing. The total portfolio exceeds £170 million in value, and its significant investments include £10.2 million in the national hub in high value photonic manufacturing at the University of Southampton; £7.2 million awarded to University College London for the photonics systems development project; £5.6 million to the University of Sheffield to research semiconductor quantum photonics; and £4.9 million to Heriot-Watt University in the hon. Lady’s constituency for its industrial doctorate centre on optics and photonics technologies.

[Joanna Cherry]

I thank the Minister for making an interesting and detailed speech and talking about the success of the university sector, particularly Heriot-Watt in my constituency. However, he will be aware that academics in centres such as the institute in my constituency are worried as a result of the Brexit vote about two things: funding and the international pool of academic and postgraduate talent on which they draw. They are looking for assurance beyond 2020 that the sources of funding and international brain power will not be lost to them.

[Joseph Johnson]

We are sensitive to such concerns, which is why the Prime Minister in her speech a week last Monday made clear statements as to her objectives for our Brexit negotiations. She detailed the importance that she puts on continued collaboration with our European research partners, and on continued access to the brightest and the best—the people who make such a difference to the success of our scientific endeavour in this country. As she underscored in her powerful speech, we are leaving the European Union, but we are not leaving Europe and we remain an outward-looking and globally focused country committed to being the global go-to centre for science and research.

The Government recognise the importance of research to the UK, which is why, at the spending review in 2015—the spending review before last—we protected the science resource budget in real terms at its 2015-16 level of £4.7 billion for the rest of this Parliament, and pledged to increase the science capital budget to £1.1 billion in 2015-16, which will rise with inflation to a total of £6.9 billion over the period 2015-21. At this year’s autumn statement we made the significant announcement that we would make an additional investment in research and development of £2 billion a year by 2020-21. As I have been at pains to say on many occasions, that is the biggest single increase in investment in R and D in this country since 1979.
