【 摘 要 】

Problem statement: In this study, Silicon based Planar Photonic Crystals (PPC) are used for the design of a 1.55 µm waveguide. Approach: Band structure calculations were performed using a block-iterative frequency-domain code to find the design parameters of both triangular and square photonic crystal slab lattices of air holes. Results: The thickness of the Silicon slab and the pore radius are varied in order to obtain optimum design parameters leading to a large and complete bandgap. Line defects are then formed in the PPC structures, by removing rows of holes, to obtain a Planar Photonic Crystal Waveguide (PPCW). Conclusion/Recommendations: The frequency domain method for Maxwells equations in a planewave basis was used to calculate the dispersion relations for the guided modes for several widths of the waveguides.
