Abstract (en)
[origin: WO2020150537A1] Designs of optical transmitters that generate laser pulses with improved optical waveform shape in generated laser pulses and provide compensation for the optical chirp of the optical transmitters. Such pulsed optical transmitters can be used in various applications, including light detection and ranging systems (LiDAR) and other optical sensing systems such as optical time-domain reflectometer (OTDR) systems, and optical communication systems.
