Abstract
Beam couplers and splitters are disclosed herein. An embodiment of a beam coupler and splitter includes a first waveguide including a bevel and a bend, and a second waveguide including a bevel complementarily shaped to the first waveguide bevel. The first waveguide bevel is configured to totally internally reflect at least some light incident thereon. The second waveguide is coupled to the first waveguide such that i) the second waveguide bevel is adjacent to at least a portion of the first waveguide bevel, and ii) a predetermined coupling ratio is achieved.
