Photonics is a foundational technology for defence, artificial intelligence, telecommunications, advanced sensing, and quantum systems. The question is whether Canada will build on an existing advantage or allow the greatest economic benefits to accrue elsewhere.

Unlike many areas of the semiconductor industry, photonics is one of the few advanced technology sectors where Canada already possesses significant expertise, infrastructure, and industrial capability. From research institutions and fabrication facilities to globally competitive companies, Canada has many of the ingredients needed to build a stronger domestic industry.

The challenge is not discovering a Canadian advantage. The challenge is scaling it.

A technology right for Canada

Semiconductors are strategically important, but not every part of the semiconductor value chain is equally accessible. Leading-edge silicon fabrication plants require very large capital investments and constant reinvestment to remain competitive. 

Photonics presents a different opportunity.

Canada has a long history of expertise in optical communications and photonic devices, dating back to the country’s telecommunications leadership. That expertise continues today through companies such as Ranovus and TeraXion, research centres such as the Centre for Optics, Photonics and Lasers (COPL) at Université Laval, the University of Ottawa’s photonics research programs, and McMaster University and UBC’s photonics laboratories. Through CMC Microsystems and the FABrIC initiative, Canada has also developed national capabilities in design support, process development, prototyping, and advanced manufacturing.

Canada should focus on areas where existing strengths can be translated into long-term industrial advantage. Photonics is one of those areas.

Why photonics matters

Photonics enables information to be transmitted, processed, and measured using light. As digital systems become more complex and data-intensive, the ability to move information quickly and efficiently becomes increasingly important. 

This is particularly relevant in three strategic sectors.

Defence and security

Modern defence systems rely on fast data movement, precision sensing, secure communications, and architectures that can operate under pressure. Photonics supports high-bandwidth communications, advanced sensors, LiDAR systems, optical gyroscopes, and secure communications infrastructure. 

As countries place greater emphasis on supply-chain security and sovereign capabilities, access to these technologies becomes a strategic consideration rather than simply a technical one.

Artificial intelligence

Artificial intelligence is rapidly increasing demand for data-centre infrastructure. The performance of AI systems depends not only on processors but also on the ability to move large quantities of data between servers, switches, memory systems, storage, and networking equipment. Photonic technologies play a growing role in these systems by enabling faster and more energy-efficient movement of information.

AI is helping accelerate the development of photonic devices through advances in design, simulation, testing, debugging, and yield optimisation. The relationship is increasingly reciprocal: AI drives demand for photonics while AI helps improve photonics development and manufacturing.

Quantum technologies

Photonics provides an important bridge to emerging quantum systems. Photon-based systems are compatible with fibre networks and field-deployable devices, which gives photonics practical advantages in areas such as secure communications and sensing. 

Canada’s leadership in quantum technologies will be strengthened by maintaining parallel strength in photonics and semiconductor packaging. A strong photonics base makes it easier to develop quantum hardware, quantum interconnects, and advanced sensing systems in Canada.

Canada has the foundations

One of the most overlooked aspects of Canada’s photonics opportunity is that many of the required assets already exist.

The Canadian Photonics Fabrication Centre (CPFC) provides national manufacturing capability for compound semiconductors and photonic devices. The facility has supported companies working on fibre optic networks, defence and aerospace, medical imaging, data centres, and advanced AI infrastructure.

Across the country, organisations such as C2MI, 3IT, Alberta nanoFAB, 4D LABS, university labs, and industrial partners contribute expertise in research, fabrication, testing, packaging, and commercialisation. 

The broader ecosystem is stronger than many Canadians realise. The challenge facing the sector is less about invention and more about creating efficient pathways from design to prototype, from prototype to production, and from production to market adoption.

Canada has many of the pieces. The greater opportunity lies in connecting them more effectively.

The commercialisation challenge

Canada has a reputation for producing excellent research. The larger challenge has always been translating that research into sustained industrial growth.

For photonics, commercialisation requires more than academic excellence. It requires access to fabrication, packaging, testing, skilled personnel, and customers willing to adopt innovative technologies.

Small and medium-sized companies often struggle to move from successful prototypes to commercial production. Delays, fragmented infrastructure, and reliance on foreign manufacturing can slow growth and increase costs.

A stronger Canadian ecosystem can help address these challenges by keeping more design, manufacturing, and intellectual property development within Canada. 

What Canada should do next

The most effective strategy is not a collection of isolated projects. It is an integrated approach that connects research, manufacturing, talent development, and industrial adoption.

Canada should focus on:

• Expanding domestic photonics manufacturing capabilities.
• Strengthening connections between design, fabrication, packaging, and testing.
• Supporting SMEs as they scale products from prototype to production.
• Aligning research investments with commercialisation opportunities.
• Developing highly qualified personnel capable of supporting long-term industry growth.
• Incorporating photonics more deliberately into defence, AI, and quantum strategies. 

The objective should not be technological leadership; it should be economic leadership built on Canadian capabilities.

A strategic opportunity

Photonics sits at the intersection of several of the most important technology trends of the next decade. Defence systems need it. AI infrastructure depends on it. Quantum technologies will increasingly rely on it.

Canada already has world-class expertise, respected institutions, established companies, and critical manufacturing assets. Few countries begin with such a strong foundation. 

The next step is not proving that photonics matters. It is ensuring that Canada captures a larger share of the value it creates.

If Canada can connect its talent, facilities, companies, and public investments into a coherent industrial strategy, photonics can become more than a research success story. It can become a durable source of economic growth, technological resilience, and national advantage.
