Welcome to Princeton Lightwave

Princeton Lightwave is the leading supplier of single-photon counting products based on indium phosphide single-photon avalanche photodiodes (SPADs). SPADs are at the core of our near-infrared Geiger-mode 3D LIDAR cameras, which provide orders of magnitude improvements in applications such as target identification, 3D mapping, ranging and navigation. These single-photon imagers also enable extreme long-distance free-space optical communications, and our SPAD-based receivers are critical components in quantum communications and sensing systems.
