Abstract
An N×N crossconnect switch is implemented without the use of waveguide crossings. In one embodiment, the N×N crossconnect switch uses two non-parallel planar arrays of 1×2 and 2×1 switching elements combined with a cylindrical reflector. In another embodiment, the N×N crossconnect switch includes an input planar array and output planar array implemented on a single wafer both having a refractive index n>1 separated by a central region having a refractive index n=1.
