Abstract: The subject matter of this specification can be implemented in, among other things, systems and methods of optical sensing for pixel multiplexing and polarized beam steering. Described, among other things, is a system that includes a light source configured to generate a light and one or more optical devices, integrated on a photonic integrated circuit, configured to impart modulation to the generated light and deliver the modulated light to an interface coupling device. The interface coupling device can include a plurality of interface couplers (ICs), each IC configured to scatter the modulated light in a direction that makes at least 5 degrees with an optical axis of lens configured to transmit the light scattered by each IC along a respective direction of a plurality of directions.
