Beyond the Chip: What Will It Take to Scale Integrated Photonics in Healthcare?

Healthcare is becoming one of the most exciting growth areas for integrated photonics. Across diagnostics, biosensing, medical imaging, ultrasound, and wearable technologies, photonic integrated circuits (PICs) are enabling healthcare systems that are smaller, faster, and more capable than ever before.

These diverse ideas were explored in PhotonDelta’s recent Integrated Photonics in Healthcare webinar, which brought together experts from across the PhotonDelta ecosystem to discuss the opportunities and challenges shaping the next generation of healthcare technologies. 

While the speakers covered a diverse range of applications, they returned to a common conclusion: the industry’s next challenge is transforming those innovations into complete healthcare systems that can be created, deployed, and adopted at scale.

Healthcare is becoming a systems opportunity

Integrated photonics is no longer confined to individual research projects or niche demonstrations. It supports an increasingly broad portfolio of healthcare applications that share many of the same technological foundations. For example, point-of-care diagnostics promise faster testing closer to patients; while biosensing platforms enable highly sensitive biomarker and pathogen detection. 

Similarly, medical imaging continues to benefit from advances in numerous technologies which are expanding the possibilities for continuous health monitoring outside of traditional clinical settings. Even mature technologies such as ultrasound are beginning to explore how integrated photonics can improve performance.

Although these applications address different clinical challenges, they all depend on the same fundamental capability: using light to generate faster, more sensitive, and more accessible information.

This transition is visible across the ecosystem, from advanced biosensing platforms to developments in OCT, point-of-care diagnostics, and photonic ultrasound. Together, these examples show that integrated photonics is moving beyond isolated technology demonstrations towards deployable healthcare systems addressing real clinical needs.

As optical functions that once required complex laboratory instruments are integrated onto semiconductor chips, opportunities emerge to reduce size, power consumption, and manufacturing cost – while improving clinical performance and accessibility.

From enabling technologies to healthcare products

If healthcare represents one of integrated photonics’ greatest commercial opportunities, then industrialisation is its defining challenge. For many years, progress was measured by individual technological advances – a more sensitive biosensor, a novel imaging technique, or an innovative photonic component. But now, moving from laboratory innovation to clinical deployment requires complete healthcare products: not individual technologies. 

Delivering healthcare products at scale requires advances in packaging, optical coupling, heterogeneous integration, manufacturing, pilot production, and systems engineering: alongside continued improvements in photonic performance.

Packaging provides a clear example. PICs cannot function in isolation; they must connect reliably with fibres, detectors, and complete diagnostic systems. Simplifying those connections while maintaining performance is essential if healthcare devices are to be manufactured economically and at high volume.

The broader opportunity, however, lies in standardisation. Although healthcare encompasses hundreds of diagnostic and monitoring applications, many are built on a relatively small number of underlying sensing approaches. Rather than developing bespoke integrated photonic technologies for every application, the industry is increasingly creating generic sensing modules that fuse photonic sensors with electronics, software, and development tools.

These modular platforms provide developers with proven building blocks that can be adapted for different healthcare applications: reducing development time while improving manufacturing efficiency. The same principle applies to heterogeneous integration, where different photonic materials and technologies are combined to deliver the performance required for specific sensing tasks. 

Combined, these approaches allow common technology platforms to be produced at scale, continually refined and reused across multiple healthcare markets, reducing costs while accelerating innovation.

The next phase of healthcare photonics

Healthcare innovation also relies on integrating multiple disciplines rather than advancing individual technologies in isolation. They depend on integrating photonics with biology, chemistry, microfluidics, and manufacturing into complete systems that satisfy the practical realities of clinical use.

Biosensing illustrates this particularly well. Sensitive photonic detection represents only one part of the overall solution. Sample preparation, biofunctionalisation, fluid handling, and optical integration all influence the final performance of the device. Similarly, advances in photonic ultrasound depend not only on innovative optical sensing concepts but also on sophisticated modelling, packaging, and system-level engineering.

No organisation possesses every capability required to bring advanced healthcare technologies to market. Strong ecosystems enable a division of labour: shared sensing platforms can be developed and manufactured at scale; while application developers, system integrators, and clinical partners focus on solving healthcare challenges. This also speeds up commercial adoption.

Across the PhotonDelta ecosystem, partner organisations are increasingly separating the development of scalable sensing platforms from application-specific product design. This allows the underlying technology to improve continuously while enabling companies to develop healthcare solutions tailored to individual clinical needs.

The future of healthcare photonics will therefore be defined less by individual breakthroughs than by the ability to industrialise shared technologies through collaboration, delivering healthcare products that improve patient care at scale.
