Abstract
A unitary injection molded waveguiding optical element is disclosed and claimed. In a preferred embodiment, there is shown an NXN star coupler 310 with a plurality of fibers 314, 316 integrally formed with the mixing body. Preferably, the fibers are continuously transitioned to the signal mixing body such that the optical path is substantially constant and the surfaces are free from lateral discontinuities.
