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.

Abstract: Photonic integrated circuits (PICs) are provided that include silicon photonic structures such as a network of horizontal and vertical bus waveguides and micro-electro-mechanical-system (MEMS) actuated switching elements configured to selectively couple light between selected horizontal and vertical bus waveguides. The PICs of the present disclosure can be applied or used in a wide variety of fields including but not limited to fiber-optic communication, photonic computing, and light detection and ranging (LiDAR). The MEMS actuated switching elements can comprise piezoelectric actuators.

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.
