Polarization and thickness dependent guiding in the photonic crystal slab waveguide.
We investigated the impact of the thickness of the twodimensional triangular photonic crystal (PC) on modal propagation along a PC slab waveguide. A single line defect optical waveguide in photonic crystal slab was designed by three-dimensional finite difference time domain method, plane wave expansion and effective index methods. The thickness of the PC slab waveguide was optimized to provide modal propagation for both TE-like and TM-like polarizations within the normalized frequency band of a/lambda=0.26-0.268.
