我们展示了一个概念，裁剪的群速度和色散特性的光在平面光子晶体波导中传播。通过扰动波导芯附近的孔，可以增加光线以下的有用带宽，并获得具有消失、正或负群速度色散和半慢光的光子晶体波导。我们实验上实现了一个绝缘体上硅光子晶体波导具有接近恒定的群速度类似于c（0）/34在11 nm的带宽下的硅线。(c)2006年美国光学学会
We demonstrate a concept for tailoring the group velocity and dispersion properties for light propagating in a planar photonic crystal waveguide. By perturbing the holes adjacent to the waveguide core it is possible to increase the useful bandwidth below the light-line and obtain a photonic crystal waveguide with either vanishing, positive, or negative group velocity dispersion and semi-slow light. We realize experimentally a silicon-on-insulator photonic crystal waveguide having nearly constant group velocity similar to c(0)/34 in an 11-nm bandwidth below the silica-line.
