Abstract

We present an analysis of a two-dimensional photonic crystal defect based coupled-cavity waveguide (D-CCW) designed in Si-air and InGaAsP-air material systems using finite-difference time-domain (FDTD) calculations. The CCW design facilitates single mode output with narrower linewidths than conventional photonic crystal (PC) waveguides. Relatively high quality factors were observed.
