    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: Bidirectional optical multiplexing employs a high contrast grating as one or both of a beam-forming lens and a relay mirror. A bidirectional optical multiplexer includes the beam-forming lens to focus light. The light is one or both of a light beam internal to and another light beam external to the bidirectional optical multiplexer. The bidirectional optical multiplexer further includes an optical filter and the relay mirror. The optical filter is to selectively pass a portion of the internal light beam at a first wavelength and to reflect portions of the internal light beam at other wavelengths. The relay mirror is to reflect the internal light beam along a zigzag propagation path between the optical filter and the relay mirror.
