    Abstract:

    Based on couple wave equation and finite-difference time-domain (FDTD) algorithm, the strong couple characteristic of 2-D photonic crystal couplers is calculated. Theoretical analysis and numerical simulated results indicate that the energy in a 2-D photonic crystal coupler can not be totally transferred between two wave-guides. Compared with the result of weak coupling theory, our result is more accurate. Supported by the Youth Science and Technology Innovation Item Foundation of Fujian Province (2001J008)
