Allegro MicroSystems Acquires Lidar/Ladar System Developer Voxtel

Facebook Twitter LinkedIn Email
Allegro MicroSystems, a developer of sensing and semiconductor technology, has acquired Voxtel Inc. Voxtel, located in Beaverton, Ore., specializes in research and delivery of electro-optical devices and laser detection and radar (ladar) systems. The company develops eye-safe indium gallium arsenide (InGaAs) photodetectors, single-photon avalanche diode (SPAD) imagers, ladar photoreceivers, and pulsed 1534-nm lasers, for military, automotive, space, and other applications.

According to Allegro CEO Ravi Vig, the acquisition will enhance Voxtel’s existing lidar portfolio for advanced driver assistance systems (ADAS) applications. The move will increase the safety, cost effectiveness, and potential for feature adoptability in cars of the future, Vig said.

Allegro’s photonics portfolio includes devices made in silicon and InGaAs, providing components for both eye-safe, long-range, 1D or 2D scanned front-facing lidar, and side- or rear-facing flash lidar.

An acronym of light detection and ranging, describing systems that use a light beam in place of conventional microwave beams for atmospheric monitoring, tracking and detection functions. Ladar, an acronym of laser detection and ranging, uses laser light for detection of speed, altitude, direction and range; it is often called laser radar.
1. The branch of physics that deals with the use of electrical energy to create or manipulate light waves, generally by changing the refractive index of a light-propagating material; 2. Collectively, the devices used to affect the intersection of electrical energy and light. Compare with optoelectronics.
