Abstract

The propagation properties of optical fields in linear and nonlinear parity-time symmetric microring coupled resonator optical waveguides are studied. The effects described include the existence of symmetry-breaking thresholds, the propagation of gap solitons in nonlinear transmission lines, and the existence of quasi-stable propagation regimes outside the broken symmetry regions.
