ABSTRACT:
An optical switching device uses a first set containing at least one MEMS mirror that receives light from a light source. A second set of MEMS mirrors are arranged to receive light from the mirror(s) of the first set. The mirrors can be independently aimed so any mirror of the first set can direct light to any mirror of the second set. A set of light collectors collects light reflected from the second set of mirrors. A collimating lens may be included between any of the mirrors and the light sources/collectors. The MEMS mirrors may be activated by being flipped down or otherwise disconnect any mirror of the first or second set.
