Optical phased arrays
Revolutionary imaging and sensing with robust Photonic Integrated Circuits
Miniature optical phased arrays (OPAs) are powering a revolution in high-resolution remote sensing. Using superfast laser beam scanning they detect both speed and distance simultaneously, driving a multi-billion dollar application in autonomous vehicle sensing. Other valuable applications include sensors for industry and satellite-based earth observation.
Forerunners to the current state-of-the-art suffered from reliance on bulky optical components and fragile moving parts. Not only were these systems difficult and expensive to manufacture at scale, but their large size and weight prevented use in many emerging applications.
The next generation of OPAs employ integrated photonics for precision operation without moving parts. The result is rugged, high performance components with costs low enough for revolutionary mass market applications.
