Abstract

An optical switch and attenuator in which any waveguide in an input waveguide bundle may be selectively optically aligned or misaligned with any waveguide in an output waveguide bundle. The waveguide bundles are attached to beams that translate the bundles through non-parallel arcs. The device provides high-performance switching and attenuation of any number of input and output waveguides.
