Paper Abstract

The conventional approach to calculate the transmission and reflection spectra of a photonic crystal (PC) waveguide device by the finite-difference time-domain method is both time and memory demanding. Here we propose a more efficient approach to obtain these spectra. First, the PC-based absorbing boundary condition is employed. Second, the reflected pulse is obtained by subtracting from a reference waveform. For a T-junction in square lattice PC, a computational cell of 40 x 36 lattice constants can be used instead of 180 x 140 lattice constants. The simulation time is reduced to only one tenth of that using the conventional approach.
