Abstract :
We propose a GaAs 2D photonic crystal tunable filter that takes advantage of rotation of a shape defect, which has a different cross-section from that of rods surrounding defect. Recent optical MEMS technology is used. Numerical simulation with boundary element method is carried out and shows the feasibility of tuning peak frequency with rotation of shape defect
