Updated November 2026. Photonics is an industrial supply chain, not only a quantum-computing architecture. This editorial directory helps engineering teams, buyers and investors compare the companies making, designing and packaging technology that uses light.
Inside Deep Tech's editorial ranking as of November 2026 considers publicly reported funding and valuation where verified, commercial traction such as deployments, revenue, named customers and contracts, and technical significance. It isn't a financial index or investment advice; the order is an editorial judgment, not a numerical score.
The scope spans silicon photonics and other photonic integrated circuits, optical I/O, datacom and co-packaged optics, lasers, lidar, foundries and industrial or medical optics. Quantum photonics is one category within a predominantly classical photonics directory.
