Engineering Fano Resonances in Photonic Structures with Nonlinear Defects and Cavities

Abstract

We study linear and nonlinear transmission of photonic networks and nanoscale devices based on directional waveguides coupled to defects or microcavities. Such systems can describe waveguides and defects in photonic crystals, nonlinear quadratic waveguide arrays, and ring-resonator structures. We demonstrate the basic principles of the scattering management through engineering Fano resonances and discuss a novel type of photonic bandgap induced by an array of Fano resonators. Show more
