ABSTRACT:
A light triggering switch is disclosed for switching the optical path of an input optical signal to a desired output optical path. A portion of an optical control signal of a predetermined wavelength is branched by a branching filter. An electrically-controlled optical switch is provided for converting the branched optical control signal into an electrical signal and for switching the optical signal to the desired output optical path in accordance with the intensity of the converted electrical signal. In place of the electrically-controlled optical switch, a nonlinear reflector type optical switch may be provided for switching the optical signal to the desired output optical path in accordance with the intensity of the branched optical control signal.
