Apparatus, method, and computer program product for structured waveguide including holding bounding region

摘要

A waveguide including a channel region defining a transmission axis and one or more bounding regions; and a plurality of magnetic constituents disposed in at least one of the regions for producing a holding magnetic field substantially parallel to the transmission axis. A method of operating a transport includes: (a) propagating a radiation signal through the waveguide generally along a transmission axis, the waveguide including a channel region defining the transmission axis and one or more bounding regions; and (b) inducing a holding magnetic field substantially perpendicular to the transmission axis using a plurality of magnetic constituents disposed in at least one of the regions wherein the holding magnetic field influences a polarization rotational change of the propagating radiation signal.
