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 light detection and ranging system including a mounting connection of a lens system in a mounting structure, including a lens system mounted in the mounting structure, the mounting connection including that the mounting structure includes at least one alignment opening, and the lens system includes a mounting shaft configured to mount the lens system in the mounting structure, wherein the alignment opening laterally surrounds the mounting shaft at least in part spaced apart in an alignment distance from the mounting shaft in the predefined alignment condition; and a spacer configured to span at least in part the alignment distance, wherein the mounting shaft is fixed in the alignment condition in the alignment opening by a first connection that fixes the spacer to the mounting structure, and by a second connection that fixes the spacer to the mounting shaft.
