Abstract

We propose the coupled ring resonator based on one-dimensional photonic crystal (1-D PC) nanocavity. The proposed structure is composed by introducing 1-D PC nanocavity into the CROW based on ring resonator, and we expect that it can achieve small group velocity. We investigate the transmission characteristics of the proposed structure by using 2-D scalar finite element method (FEM) for periodic waveguide analysis. We obtained the group velocity vg = 0.033 c with c being light velocity in vacuum because of combining 1-D PC nanocavity and CROW based on ring resonator. Moreover, we consider reduction of footprint of the proposed structure for photonic integration.
