CONTROLLING TUNNELING MODES BY A PHOTONIC QUANTUM WELL STRUCTURE BASED ON ZERO EFFECTIVE PHASE GAP

Abstract

Light propagation through one-dimensional photonic quantum well (PQW) structures consisting of single-negative (SNG) materials is investigated theoretically. It is found that, based on the zero-effective-phase gap mechanism, the resonant tunneling modes can be manipulated to realized multiple channeled filters which are not only weakly dependent on the incident angle and polarization, but also insensitive to the deviation of the photonic barrier thickness. These properties are advanced to conventional PQW structures and the physical reason for the remarkable features of the proposed PQW structure is analyzed.
