    Abstract: A chip-scale scanning lidar includes a two dimensional (2D) scanning micromirror for a transmit beam and a 2D scanning micromirror for a receive beam, a laser diode and a photodetector, a first waveguide and first grating outcoupler coupled to a front facet of the laser diode, a second waveguide and a second grating outcoupler coupled to a rear facet of the laser diode on a substrate. A first fixed micromirror, a second micromirror, a third micromirror, and a focusing component are in a dielectric layer bonded to the substrate over the laser diode and photodetector. The photodetector is optically coupled to the second fixed micromirror and the third fixed micromirror for coherent detection.
