Abstract :
Finite Difference Time Domain (FDTD) analysis is effectively applied to investigate the transmission of the transverse electric polarized pulses in a 90deg bend photonic crystal waveguide. A comparison with a Time Domain Beam Propagation Method (BPM) based on finite clement scheme is made and excellent agreement is achieved. Moreover, a detailed study of photonic crystal couplers has been carried out. A series of simulations are performed to determine by how much the radius of holes would have to be tuned to result in realizing the functions of the truth tables of the proposed optical directional couplers.
