NeoPhotonics 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 (light detection and ranging) applications. NeoPhotonics SOAs and NLW lasers feature 1550nm wavelength SOAs with >24 dBm (>250mW) output power along with 1550nm NLW-DFB lasers that enable automotive Lidar systems to “see” farther.
Advanced “coherent” technology pioneered by NeoPhotonics can greatly increase the range and sensitivity of LIDAR systems by measuring the phase of the reflected light. Coherent Lidar systems are fabricated using Photonic Integrated Circuits (PICs) powered by low phase and intensity noise semiconductor lasers and high output power semiconductor optical amplifiers. Narrow linewidth and low phase noise lasers enable the precise phase measurements required, with optical amplifiers to boost the optical signal power for long reach detection.
