✦ Synopsis

A one-to-two splitter for self-collimated beams in photonic crystal (PC) is designed by inserting one row of line defects. Finitedifference time-domain (FDTD) method is used to simulate the light propagation process. Our systematical studies show that the splitting ratio is a function of the airholes size of the line defect radius, and stays fairly constant as a function of frequency. Furthermore, it is shown the numerical results can be analyzed by coupled-mode theory.

An explicit method is presented for the analysis of guided wa¨es in a line defect channel in a two-dimensional photonic crystal. It can predict, e.g., the minimal channel width for allowing a wa¨e to propagate in the channel at a frequency in the stopband of the photonic crystal. The theoretical pre
