Abstract: Disclosed herein are light detection and ranging (LIDAR) systems and methods for manufacturing the same. The LIDAR systems may include microelectronics packages that may include a chassis, an insert, a photonic integrated circuit (PIC), and a lid. The chassis may define an opening. The insert is sized to be received in the opening. The insert is made of a thermally conductive material. The PIC is attached to the insert. The lid is connected to the chassis and defines a cavity that encases the PIC. Both the insert and the lid form thermally conductive pathways away from the PIC.

Abstract: A multi-wavelength transmitter suitable for use in LiDAR applications where an array of output beams comprising a plurality of wavelengths is spatially modulated with low amplification requirements. The optical transmitter comprises one or more light sources, such as a plurality of laser emitters operable at different wavelengths. The light source(s) are coupled, for example through one or more planar waveguides, to an optical switch network comprising one or more switches. The switch network is to route, in a time divided manner, source beams to individual ones of a plurality of switch output ports thereby modulating the wavelength of a beam exiting each of the output ports. A plurality of output couplers, for example comprising edge coupled spot size convertors, are coupled to separate ones of the switch output ports, for example through one or more planar waveguides and/or one or more beam splitters.
