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.
