Abstract

A lidar system includes a photonic chip including a light source and a transmit beam coupler to provide an output signal for transmission. The output signal is a frequency modulated continuous wave (FMCW) signal. A transmit beam steering device transmits the output signal from the transmit beam coupler of the photonic chip. A receive beam steering device obtains a reflection of the output signal by a target and provides the reflection as a received signal to a receive beam coupler of the photonic chip. The photonic chip, the transmit beam steering device, and the receive beam steering device are heterogeneously integrated into an optical engine.
