  • Chip-scale optical phased array for projecting visible light
    Patent number: 11662643
    Abstract: Methods and systems are described for adjusting an optical signal. An example device can comprise a plurality of waveguides. The device can comprise an interference structure optically coupled to the plurality of waveguides and configured to receive an optical signal and distribute the optical signal to the plurality of waveguides as a plurality of optical signals. The device can comprise a plurality of phase shifters coupled to corresponding waveguides of the plurality of waveguides and configured to adjust the phase of one or more of the plurality of optical signals. The device can comprise a plurality of emitters optically coupled to corresponding outputs of the plurality of phase shifters and configured to output the adjusted plurality of optical signals. The adjusted plurality of optical signals can be output as light patterns reconfigurable in at least one dimension.
