A beam steering system includes a light source configured to generate an optical beam at various wavelengths. An array of emitters receives the beam and selectively emits the beam. An optical device receives the beam and directs the beam into an external environment of the beam steering system. The beam is directed into the external environment at different angles corresponding to a location of the emitter and the wavelength of the beam. As a result, the beam steering system steers the beam for a three-dimensional scan of the external environment.

Photonic beam steering device with wavelength sweep

System and methods for Light Detecting and Ranging (LIDAR) are disclosed. The LIDAR system includes a light source configured to generate a tunable beam, an optical beam steering device positioned to receive at least a portion of the beam and configured to sweep the beam over a range of angles in a field of view (FOV) wherein each discrete frequency of the beam corresponds to a different angle in the FOV, a detector configured to generate an interference signal based on the received portions of the beam, and a processor communicably coupled to the detector. The processor is configured to cause the light source to tune the tunable beam from a first frequency to a second frequency and to calculate a range of an object corresponding to either the first frequency or the second frequency within the FOV.
