ABSTRACT:
An optical switch globally minimizes maximum tilt angles used to route optical signals from input to output by disposition of an input array of first tiltable micromirrors within a first boundary typically having top-bottom reflection symmetry and left-right reflection symmetry and by disposition of an output array of second tiltable micromirrors within a second boundary a symmetry which matches the symmetry for the input array, the output array and the input array being disposed opposing one another and normal to parallel central axes and further being offset from one another in the plane of the normals to the arrays, so that a collimated beamlet impinging on the center the input array and reflected off at an equivalent angle intersects the output array at an offset.
