Abstract: Systems and techniques associated light detection and ranging (LIDAR) applications are described. In one representative aspect, techniques can be used to implement a packaged semi-conductive apparatus is disclosed. The apparatus includes a substrate; a diode die carried by the substrate and positioned to emit an electromagnetic energy beam; and a shell coupled to the substrate to enclose the diode die. The shell includes an opening or a transparent area to allow the electromagnetic energy beam emitted from the diode die to pass through the shell.
