High precision optical measurement systems

Fibre-based quantum hardware and Terahertz spectroscopy

A few things we’re great at

We operate in two distinct fields
Ultra-stable stabilization systems applied to fibre-based interferometers
Ultra-broadband terahertz detection for unambiguous detection of materials and chemicals


We provide a fiber-based interferometric stabilization system that defines a new paradigm in the development of high-precision optical sensors and quantum technologies 



We provide an ultra-broadband terahertz detection system allowing for the unambiguous identification of materials and chemicals on a range of 0.1 to 10 THz


Ki3 Photonics is an INRS-EMT spin-off company
