Scanning multiple lidar system output signals

Abstract

A LIDAR system has a switch configured to direct a switch signal to one of multiple different alternate waveguides such that the alternate waveguide to which the switch directs the switch signal receives the switch signal from the switch. The switch signal carries multiple different channels. The system also includes an optical grating that receive multiple different channel output signals. Each of the channel output signals includes light from the switch signal and carries a different one of the channels. The optical grating outputs the channel output signal such that a direction that each of the channel output signals travels away from the optical grating changes in response to a change in the alternate waveguide to which the switch directs the switch signal.
