Loss Reduction Mechanism for Coupled Cavity Waveguides in One-Dimensional Photonic Crystals

Abstract

This paper presents a loss reduction mechanism for coupled cavity waveguides (CCWs) relying on 1-D photonic crystals microcavities. The mechanism is based on structural modification in the vicinity of the cavity defects. With appropriate modifications, the tangential wavenumber components of the leaky guided modes, which can couple to cladding modes, can be… (More)
