Micro-optical crossbar switching network e.g. electronic and fiber optic telecommunications networks, for optical distribution and switching optical information channels, has optical channels interlaced and switched in optical arrangement

摘要

The network has an arrangement formed as combination of planar integrated free space optics and flexible day and/or night mirrors on basis of planar coupled digital mirror device-modules (4) and micro lens arrays. A geometric division and separation of optical channels are realized by the combination of divergent emission of light and a glass fiber-matrix on a downstream off-axis micro lens array. A spatial interlacing and flexible switching of the optical channels are realized in an optical arrangement, and binary amplitude-modulated holograms are produced by a micro mirror.
