Abstract
Systems for switching optical signals are disclosed. Such a system may include a splitter and a plurality of polarizing filters. The splitter may be configured to receive emitted light and duplicate the emitted light into a plurality of light copies. Each polarizing filter may have a polarization and may be operably connected to the splitter. In addition, each polarizing filter may be configured to receive at least one of the plurality of light copies, filter the at least one of the plurality of received light copies such that light having a similar polarization as that of the polarizing filter passes through the polarizing filter, and output one of a plurality of outputs.
