Performance evaluation of an optical drop filter based on simple homogeneous photonics crystal resonator

In this paper we proposed a novel drop filter structure based on Photonic Band Gap (PBG) for the 1550nm communication wavelength. The filter is designed and then simulated using Finite Element Method (FEM) and Plane Wave Expansion Method (PWEM) method. The filter shows 91% efficiency at the mentioned wavelength. We also analyzed how the target wavelength can be varied by changing various aspects of the structure. The design utilizes all homogeneous method which is easier to fabricate and introduce in photonic integrated circuit.
