| 中文摘要 | the propagation losses in single-line defect waveguides in a two-dimensional (2d) square-lattice photonic crystal (pc) consisted of infinite dielectric rods and a triangular-lattice photonic crystal slab with air holes are studied by finite-difference time-domain (fdtd) technique and a pade approximation. the decaying constant beta of the fundamental guided mode is calculated from the mode frequency, the quality factor (q-factor) and the group velocity v(g) as beta = omega/(2qv(g)). in the 2d square-lattice photonic crystal waveguide (pcw), the decaying rate ranged from 10(3) to 10(-4) cm(-1) can be reliably obtained from 8 x 10(3)-item fdtd output with the fdtd computing time of 0.386 ps. and at most 1 ps is required for the mode with the q-factor of 4 x 10(11) and the decaying rate of 10(-7) cm(-1). in the triangular-lattice photonic crystal slab, a 10(4)-item fdtd output is required to obtain a reliable spectrum with the q-factor of 2.5 x 10(8) and the decaying rate of 0.05 cm(-1).
