compiled: June 4, 2015We consider an optical fiber with nanoscale variation of the effective fiber radius supporting whispering gallerymodes slowly propagating along the fiber, and reveal that the radius variation can be designed to supportreflectionless propagation of these modes. We show that reflectionless modulations can realize control oftransmission amplitude and temporal delay, while enabling close packing due to the absence of cross-talk, incontrast to conventional potentials.OCIS codes: 060…
