WebWhat is photonic crystal waveguide? Photonic crystal waveguides (PCW) are one of the promising examples of PhCs applications at micron and submicron length-scales. PCW can be formed by removing one or several lines of scatterers from the PhC lattice. Light confinement is obtained due to a complete photonic bandgap (PBG). WebIn this theoretical study, a line-defect photonic-crystal waveguide hosted in an annular photonic crystal was demonstrated to provide high-performance slow light with a wide band, low group-velocity dispersion, and a large normalized delay-bandwidth product. Combined with structural-parameter optimization and selective optofluid injection, the normalized …
