Paper Abstract

We show theoretically that the upper and lower cutoff frequencies in a two-dimensional photonic crystal coupled-cavity waveguide (CCW) can be moved synchronously by changing two configuration parameters of the waveguide simultaneously. The CCW is formed in a two-dimensional photonic crystal (2-D PhC) consisting of a square array of dielectric rods in the air. Efficient methods have been demonstrated for moving the two cutoff frequencies in the same direction over equal distances up to 25.7% of the photonic band gap. The results can be applied to the design of integrated optical devides based on photonic crystal waveguides.
