The photon economy: why smart money is paying attention
The rise of the so‑called photon economy is reshaping how leading investors think about the next decade of deep tech. As data volumes explode, energy systems electrify and manufacturing digitises, demand for faster, more efficient ways to transmit, sense and process information is surging. This is where photonics – technologies that generate, control and detect light – is moving from niche to necessity.
Andy Bloxam, a Partner at the UK-based investment firm Foresight Group, argues that the world is at a tipping point. In his view, the combination of maturing research, falling component costs and new industrial use cases means that photonics is ready to break out of the lab and into large, scalable markets. For investors willing to understand the technology stack and time horizons, he believes this could be one of the most attractive deep-tech opportunities of the 2020s.
What photonics actually is – and why it matters now
At its core, photonics is about using light instead of electrons to carry information or perform tasks. It underpins everything from fiber‑optic communications and LiDAR sensors to laser manufacturing, quantum technologies and next‑generation medical imaging. For decades, these systems have been critical yet largely invisible infrastructure, often treated as specialist hardware rather than a general‑purpose technology platform.
That perception is changing. The limitations of traditional semiconductor scaling, rising data‑centre energy consumption and the need for ultra‑precise industrial processes are all pushing industries toward light‑based solutions. Photonics promises:
- Orders‑of‑magnitude improvements in bandwidth and latency for communications and computing.
- Higher precision and lower waste in advanced manufacturing.
- New capabilities in autonomous systems, biotech and climate monitoring.
For venture capital, this translates into a broad surface area of opportunity across telecoms, cloud infrastructure, automotive, defence, healthcare and clean energy.
Why investors are only now waking up to photonics
Despite its importance, photonics has historically been underrepresented in mainstream venture capital portfolios. According to Andy Bloxam, there are several reasons why investors have been slow to move:
- Hardware bias: Many generalist funds have preferred software‑only businesses with lighter capital requirements and faster scaling, overlooking deep‑tech hardware where photonics sits.
- Complexity: Photonics demands an understanding of optics, materials science and semiconductor fabrication, disciplines that can feel remote from the typical SaaS or fintech playbook.
- Longer timelines: Commercialising new photonic components or integrated systems often takes longer than launching a digital product, which can deter funds with shorter investment horizons.
Yet the environment is shifting. Strategic buyers in telecoms, automotive and cloud computing are actively seeking differentiated IP, governments are prioritising deep‑tech sovereignty, and specialist fabrication capacity is improving. As a result, what once looked like an over‑technical backwater is starting to resemble a strategic frontier.
A VC playbook for the photon economy
Foresight Group and Partner Andy Bloxam outline a pragmatic approach for investors who want to participate in the photon economy without taking unbounded risk. The emerging playbook combines careful technology selection with disciplined market focus.
Back platforms, not just components
Rather than funding one‑off optical components, sophisticated investors are seeking platform technologies that can serve multiple end markets. Examples include:
- Silicon photonics platforms that integrate optical and electronic functions on a single chip for data centres and telecoms.
- Reconfigurable optical engines that can be tuned for different sensing or imaging applications.
- Manufacturing toolchains that enable other companies to design and fabricate photonic devices more easily.
This platform orientation increases the chance of building large, defensible businesses rather than niche component suppliers.
Focus on system‑level value, not specs
One of the classic mistakes in deep tech is to over‑index on technical specifications. The playbook that Andy Bloxam advocates is to translate performance gains into hard economic value for customers:
- How much energy consumption can a photonic interconnect save in a hyperscale data centre?
- What reduction in unit cost or scrap rate does a laser‑based manufacturing process deliver?
- How does improved resolution or range translate into safety and regulatory advantages for autonomous vehicles?
Investors who can link photonic performance to clear ROI and payback periods will be better positioned to judge which startups can cross from prototype to profitable deployment.
Blend capital with industrial partnerships
The photon economy is inherently cross‑sector. Successful photonics startups often depend on close collaboration with large OEMs, infrastructure providers and manufacturing partners. The VC playbook therefore emphasises:
- Early design‑in partnerships with strategic customers.
- Access to pilot production and foundry capacity.
- Co‑development agreements that de‑risk scale‑up while validating demand.
Funds like Foresight Group see value in acting as connectors between photonics startups and the industrial ecosystem, not just as providers of capital.
How the UK could lead the photon economy
The UK already has strong foundations in optics, quantum technologies and semiconductor research, anchored by universities such as Cambridge, Oxford and Southampton. According to Andy Bloxam, turning this scientific strength into commercial leadership requires a coordinated effort across policy, capital and industry.
Leverage world‑class research
The UK’s photonics research base produces high‑quality intellectual property, but too much of it is licensed or acquired overseas. Strengthening technology transfer, supporting spin‑out formation and providing early‑stage deep‑tech funding are critical steps to keep value creation onshore.
Build specialised infrastructure
Photonics ventures need access to advanced fabrication facilities, test labs and packaging capabilities. Public‑private investment in shared infrastructure can reduce capital intensity for startups, making the UK a more attractive location to build and scale photonics companies.
Align capital with long‑term horizons
Winning the photon economy will not fit neatly into three‑year exit cycles. UK investors, including pension funds and institutional allocators, will need to support vehicles that can hold deep‑tech assets for longer, while government programmes can help crowd in private capital through co‑investment and risk‑sharing mechanisms.
What most investors are still missing
Despite growing interest, many investors still underestimate how pervasive the photon economy could become. Photonics is not just a single vertical; it is an enabling layer that can reshape cloud computing, AI infrastructure, mobility, healthcare diagnostics and industrial automation. Funds that treat it as a narrow hardware niche risk missing a wave of value creation akin to the early days of mobile or cloud.
For Andy Bloxam and Foresight Group, the message is clear: the UK has the ingredients to become a global hub for photonics, but the window to act is finite. As smart money begins to move, those with a structured playbook for the photon economy – and the patience to back it – may find themselves holding some of the most strategically important assets of the coming decade.
