Abstract
Optical switch based on a micro-minor device such as a DMD configured to simultaneously switch light from N inputs to M outputs with switching times of about 10 microseconds, where N and M are generally greater than one. The minors of the device are oriented according to a pattern calculated based on a Fourier Transform of spatial distribution of M outputs such as to form, in diffraction of light incident on the device, and diffraction light pattern that in the output plane is substantially congruent with the spatial distribution of M outputs. The device can be configured as a modulator of amplitude and/or a modulator of phase of incident light wavefront.
