Abstract: In the present study, the simulation and analysis have been presented for novel optical wavelength channel drop filter based on 2D fractal ring resonator structure using photonic crystal technologies. The design of 2DPC (two Dimensional Photonic Crystal) channel drop filter is done using FDTD (Finite Difference Time Domain) method. The photonic bandgap is obtained with the help of Plane Wave Expansion (PWE) method. The parameters of channel drop filter have been optimized for 1591 nm mostly used telecommunication wavelength with refractive index of 3.16 using (InP) Indium Phosphide dielectric material. The number of rods in X and Z directions are taken as 21 and 20, respectively with lattice constant of 540 nm and radius of dielectric rod as 0.1 μm. From the simulation, it found that, by varying the parameters of Photonic Crystal Ring Resonator (PCRR) (i.e., scatter rod radius). The proposed design gives around 100% dropping efficiency at 1591 nm wavelength with a good quality factor about 352. The ultra-compact structure is proposed which can be valuable for communication applications and PICs.
