✦ Synopsis
We have investigated the self-imaging phenomena based on the field distribution in two-dimensional multimode photonic crystal waveguides (PCWs) by the finite-difference time-domain (FDTD) method. The new self-imaging conditions are given for the mirrored images and the direct images. The self-imaging distributions in multimode PCWs can be explained by the new selfimaging conditions and the superposition of ''sub-images''. The results of numerical simulation show a good agreement with the theoretical predictions.
