  • Publication number: 20240011353
    Abstract: An integrated-optics MEMS-actuated beam-steering system is disclosed, wherein the beam-steering system includes a lens and a programmable vertical coupler array having a switching network and an array of vertical couplers, where the switching network can energize of the vertical couplers such that it efficiently emits the light into free-space. The lens collimates the light received from the energized vertical coupler and directs the output beam along a propagation direction determined by the position of the energized vertical coupler within the vertical-coupler array. In some embodiments, the vertical coupler is configured to correct an aberration of the lens. In some embodiments, more than one vertical coupler can be energized to enable steering of multiple output beams. In some embodiments, the switching network is non-blocking.

  • Publication number: 20230393243
    Abstract: The present disclosure is directed to imaging LiDARs monolithic integration of focal plane switch array LiDARS with CMOS electronics. The CMOS wafer contains electronic circuits needed to control the focal plane array, e.g., digital addressing circuits and MEMS drivers, as well as circuits to amplify and process the detected signals, e.g., trans-impedance amplifiers (TIA), multi-stage amplifiers, analog-to-digital converters (ADC), digital signal processing (DSP), and circuits to communicate with external systems. Methods of use are also provided.

  • Publication number: 20220373688
    Abstract: The present disclosure is directed to imaging LiDARs with optical antennas fed by optical waveguides. The optical antennas can be activated through an optical switch network that connects the optical antennas to a laser source to a receiver. A microlens array is positioned between a lens of the LiDAR system and the optical antennas, the microlens array being positioned so as to transform an emission angle from a corresponding optical antenna to match a chief ray angle of the lens. Methods of use and fabrication are also provided.
