    Abstract: Beam couplers and splitters are disclosed herein. An example of a beam coupler and splitter includes a first waveguide having a first waveguide bevel and a bend, the first waveguide bevel to totally internally reflect at least some light incident thereon. A second waveguide includes a second waveguide bevel complementarily shaped to the first waveguide bevel, the second waveguide being coupled to the first waveguide such that i) the first waveguide bevel is offset from the second waveguide bevel so that a first portion of the first waveguide bevel is in direct contact with a first portion of the second waveguide bevel, a second portion of the first waveguide bevel is exposed, and a second portion of the second waveguide bevel is exposed, and ii) a predetermined coupling ratio is achieved.

    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.
