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.

Abstract: An apparatus, method, computer program product, and propagated signal for a transport. The transport including: a waveguide including a guiding region and one or more bounding regions for enhancing containment of transmitted radiation within the guiding region, the waveguide including an input region and an output; a plurality of constituents disposed in the waveguide for enhancing an influencer response attribute of the waveguide; and a polarization system coupled to the input region, the input polarizer system producing a wave component having a supported polarization disposed at a predetermined angular orientation at the input from an input radiation source including a set of source wave components each having one of a set orthogonal polarizations wherein the input polarizing system operates on the source wave components to pass source wave components having polarizations matching the supported polarization.

Abstract: An apparatus and method for a transport. The transport including a waveguide including a guiding region and one or more bounding regions for enhancing containment of transmitted radiation within the guiding region, a portion of the waveguide defining a plurality of voids; and a gas disposed in the plurality of voids to enhance an influencer response attribute of the waveguide. A method of operating the transport includes: a) propagating a radiation signal through a waveguide including a guiding region and one or more bounding regions for enhancing containment of transmitted radiation within the guiding region, a portion of the waveguide defining a plurality of voids; and b) enhancing a response of the radiation signal to an influencer applying an influence on the waveguide using a gas disposed in the plurality of voids.
