A two-dimensional (2D) triangular lattice photonic crystal coupled-cavity waveguide is designed and optimized. The transmission spectrum of the PC waveguide with TE polarization is calculated by using the finite-difference time-domain (FDTD) method, and the group velocity of c/131.18 at the wavelength is obtained. Through optimizing the parameters of photonic crystal waveguide, different resonance length are obtained by changing the number of the continous air holes. The smallest group velocity is obtained to be c/2209 in the coupled-cavity waveguide with 15 air holes. The mechanism of slow light in the coupled-cavity waveguide of photonic crystal is analyzed.

Encoder with a hexagonal lattice photonic crystal was performed by OCDMA simulation model. Filtering of photonic crystal cavity was used for encoding in spectral domain, and the distance between the dot defects was used for encoding in time domain because of its slow light effects caused by dispersion, whose time delay reached orders of ns magnitude. According to the simulation, the BER of OCDMA system with PC encoder is 10-23, while BER is 10-18 in the system with FBG encoder. By contrast, it is indicated that PC encoder requires strict demands on its own structure. With mismatching of encoder and decoder in receiving terminal, BER decrease to 10-7, and the performance of OCDMA system is serious affected.
