A novel approach for modeling photonic crystal circuits is proposed. In this approach, the effective length of photonic crystal waveguide between two devices is estimated. The frequency response of the photonic crystal circuit is modeled as a Fabry-Perot cavity. An example of double 90-degree bend is analyzed by the approach. The results have great agreement with those obtained by finite-difference time-domain method.
