Super-resolution optical frequency-domain interferometry
Resolve distributed reflection and loss to help locate anomalies in connectors, coupling interfaces and waveguides, adding spatial information to end-to-end parameters.
COMPANY OVERVIEW
Master the Spectrum
Measure at Scale
Keyhole Photonics (Wuhan) Instruments Co., Ltd.
Make Invisible Optical Paths
A Source of Traceable Evidence.
We are a precision optical test instrument company serving high-speed optical interconnects, founded by a team spanning optoelectronics, instrumentation R&D, industry operations and investment. From China's Optics Valley, we combine optics, electronics, algorithms and software for device development and manufacturing.
OUR FOCUS
Measure the Difference.
Understand Its Origin.
Higher bandwidth and denser integration make overall device performance insufficient to explain every anomaly. R&D and manufacturing teams need to relate results to optical locations, structural interfaces and process changes.
Keyhole Photonics focuses on silicon photonic chip testing across optical communications, silicon photonics, and photonic computing and quantum photonics. We investigate light propagation using super-resolution coherent optical measurement and relate structure to performance through optical digital twins, supporting traceable R&D, process optimization and production quality assessment.
