摘要: Previously, we proposed and demonstrated chirped photonic crystal waveguides, in which some structural parameters are gradually changed so that the band characteristic is smoothly shifted. In this letter, discuss an optical delay line composed of two index-chirped waveguides a directional coupler structure. A large realized by low average group velocity
