Abstract

Bandgap and defect mode are important properties of two-dimensional (2D) photonic crystal, which determine the application of photonic crystal. At present, researchers have done a large amount of studying on point defect and line defect photonic crystal. In this paper, we introduce multi-point defects into 2D photonic crystal by removing medium rods (InGaAsP), and then simulate their bandgap and mode field using plane wave method (PWM). The simulation results are useful to design the multi-wavelength photonic crystal laser.
