Optical switch with reduced beam divergence


An optical switch, optical switching method, and a switched optical communication system include at least one micro-mirror in a path along which an optical signal propagates between first and second optical waveguides. Further provided is a refractive material through which the optical signal propagates. The refractive material has a refractive index greater than the refractive index of air. The refractive index of the refractive index may be less than or equal to a refractive index of the optical waveguides.
