Abstract: A system and method of optical switching utilizing a reflection device, the switch is disclosed. The system can include: an optical transmission path having an optical transmission medium, an input-side end and a first and a second output-side end; a radiation source associated with said input-side end for emitting a primary optical signal being coupled into said transmission path; a reflection device with the ability to be turned on and off selectively for receiving the primary optical signal and converting the primary optical signal into a secondary, modulated optical signal being reflected and coupled back into the second output-side end when the reflection device is on and wherein the primary optical signal is coupled into the first output-side end when the reflection device is off. The optical switch can contain mirrors that turn on and off, or are fixed in place while the switch is movable.
