What Are Photonics Wafers?
Photonics wafers are high-performance semiconductor and optical substrates used to fabricate devices that generate, guide, detect, and manipulate light. Unlike conventional electronic circuits that rely solely on electrons, photonic devices transmit information using photons, enabling higher bandwidth, faster data transfer, and lower power consumption for next-generation communication and sensing technologies.
UniversityWafer supplies research-grade substrates for silicon photonics, photonic integrated circuits (PICs), optical waveguides, lasers, modulators, photodetectors, quantum photonics, and biomedical imaging applications.
