摘要：

Photonic crystal tapers have been designed for coupling of light from ridge waveguides into low group velocity photonic crystal channel guides. The coupling efficiency is increased from 3% (case of butt-coupling) to 97% for frequencies in the band-edge region, corresponding to a group index close to 100, as predicted using 2D finite-difference timedomain simulations.
