Subwavelength-Diameter Silica Wire and Photonic Crystal Waveguide Slow Light Coupling
2007
Active and Passive Electronic Components
Preserved Fulltext
Counter-directional coupling between subwavelength-diameter silica wire and single-line-defect two-dimensional photonic crystal slab waveguide is studied numerically using parallel three-dimensional finite-different time-domain method. By modifying silica wire properties or engineering photonic crystal waveguide dispersion band, the coupling central wavelength can be moved to the slow light region and the coupling efficiency improves simultaneously. One design gives 82% peak power transmission
