Abstract: One example relates to an optical engine comprising an optical waveguide. The optical waveguide can comprise a total internal reflection (TIR) edge to change direction of an optical light beam to an angle parallel to a top surface and a bottom surface of the optical waveguide. The optical waveguide can also comprise a plurality of aligning holes extending from the top surface to the bottom surface of the optical waveguide. The optical engine can comprise a substantially transparent slab underlying the optical waveguide. The slab can also comprise a micro lens to collimate the optical light beam. The slab can further comprise a plurality of aligning pins extending perpendicular from a top surface and bottom surface of the slab. Each of the plurality of aligning pins can extend through a respective one of the plurality of aligning holes.

Abstract: A system includes an optical transmitter package comprising an optical transmitter to generate optical transmission signals based on electrical transmission signals. The system also includes an optical receiver package comprising an optical receiver to generate electrical reception signals based on optical reception signals. The system further includes a printed circuit board (PCB) on which the optical transmitter package and the optical receiver package are mounted. The PCB includes a heat generating circuit component. The optical transmitter package can be mounted to the PCB to subjected to less heat from the heat generating circuit component than the optical receiver package.
