Abstract

In this paper enhanced coupled cavity Photonic Crystal waveguides are our concern and will be analyzed and discussed. The main feature of this proposed device is lowering group velocity up to 0.05 and obtaining higher bandwidth up to 0.017 and in the optimum situation leads to a higher group velocity bandwidth product (GBP) up to 0.33 which is mainly considerable among reported values. Simulated device consists of square periodic photonic crystal pattern. Simulations are based on Plane Wave Expansion (PWE) numerical analysis method. The results of simulations demonstrate that the group velocity will be minimum, in the pattern with ra=0.45a and also the maximum GBP occurs at ra=0.3a and for this state the storage time per unit length is 1ms/36000m.
