Abstract

An apparatus and method for a substrate-supported transport system with a radiation baffle system. The transport includes a semiconductor substrate, the substrate supporting: an integrated waveguide structure, the waveguide structure including a guiding channel and one or more bounding regions for propagating a radiation signal from an input to an output; and an influencer system, responsive to a control and coupled to the waveguide structure for independently controlling an amplitude-influencing attribute of the radiation signal within an influencing zone; and a recursion system for periodically returning the radiation signal into the influencing zone for periodically influencing the amplitude influencing attribute of the radiation signal. The operating method includes a) propagating a radiation signal through a waveguide structure supported in a substrate, the waveguide structure including a guiding channel and one or more bounding regions for propagating the radiation signal from an input to an output; and b) recursing the radiation signal through an influencing zone for periodically influencing an amplitude influencing attribute of the radiation signal.
