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.
