Abstract

We present here a numerical study of an optical Fabry-Perot filter made within triangular symmetry 2D photonic crystal by using the finite difference time domain method. Devices that are structure based on microcavities have been studied using direct input and output coupling through channel waveguides including size-graded holes on both sides of the microcavitiy. From a transmission calculation, a very high-Q-factor value has been achieved at λ=1.50086μm.
