Abstract
A photonic switching device has a first set of optical waveguides, a second set of optical waveguides, and an arrangement of controllable deformable micromirrors for selectively completing an optical path between any one of the first set of waveguides and any one of the second set of waveguides. Typically, the deformable mirrors are arranged in a pair of opposed grid arrays with the input and output waveguides extending along respective rows and columns in the manner of a crosspoint switch, but with the rows and columns intersecting at an oblique angle.
