Abstract

An apparatus and method for a switch for a radiation signal, the switch including a first waveguiding channel having a guiding region and one or more bounding regions coupled to the guiding region, the first waveguiding channel including a first lateral guiding port in a portion of the bounding regions, the lateral guiding port responsive to an attribute of radiation propagating in the channel to selectively pass a portion of the radiation therethrough; and an influencer, coupled to the first waveguiding channel, for controlling the attribute of the radiation. A method of operating the switch includes: a) propagating the radiation signal in a first waveguiding channel having a guiding region and one or more bounding regions coupled to the guiding region, the first waveguiding channel including a first lateral guiding port in a portion of the bounding regions, the lateral guiding port responsive to an attribute of radiation propagating in the channel to selectively pass a portion of the radiation therethrough; and b) influencing the radiation signal in a portion of the guiding region to control the attribute wherein a first value of the attribute passes a first amplitude for the radiation signal and a second value of the attribute passes a second amplitude for the radiation signal.
