NeoPhotonics Corporation (NYSE: NPTN), a designer and manufacturer of advanced hybrid photonic integrated circuit based modules and subsystems for bandwidth-intensive, high speed communications networks, has announced that it is sampling high power Semiconductor Optical Amplifiers (SOAs) and Narrow Linewidth (NLW) Distributed Feedback Lasers (DFB) lasers for long range automotive Lidar applications, the company said.
NeoPhotonics SOAs and NLW lasers operate in eye-safe wavelength regions, and these offerings feature 1550nm wavelength SOAs with >24 dBm (>250mW) output power along with 1550nm NLW-DFB lasers that enable automotive Lidar systems to “see” considerably farther than 200 meters, thereby significantly enhancing safety.
Current Lidar systems for autonomous vehicles use expensive discrete optical components and employ direct detection measurement of the reflected light intensity, which limits range and sensitivity. Next generation Lidar systems will use “coherent” technology, which was pioneered by NeoPhotonics for communications networks, to greatly increase the range and sensitivity by measuring the phase of the reflected light. Coherent Lidar systems are fabricated using chip-scale manufacturing to reduce costs and enable high volume.
NeoPhotonics is a designer and manufacturer of optoelectronic solutions for the highest speed communications networks in telecom and datacenter applications. The company´s products enable cost-effective, high-speed data transmission and efficient allocation of bandwidth over communications networks. For additional information visit www.neophotonics.com.
