We present the numerical simulation of an all-optical demultiplexer using 2D photonic crystal ring resonators for optical communications systems. The structure consists of three ring resonators, one bus waveguide, and three drop waveguides. The photonic crystal of the demultiplexer has a square-shaped structure made up of silicon rods with lattice constant a = 548 nm, filling factor(r/a) of 0.18, where r is the radius of the rods, and linear refractive index of n = 3.4. The structure can filter three standard wavelengths with 4.2 nm channel spacing between the wavelengths. From the simulations, the mean quality factor and transmission efficiency of our structure are computed to be respectively 4936 and 96.5%, at wavelengths very close to 1.55 μm. The minimum and maximum values of crosstalk are −18.6 dB and −34.6 dB, respectively. The footprint of the device is 293.7 μm 2 , which is suitable for photonic integrated circuits. The optical characteristics and the behavior of the proposed demultiplexer have been achieved by means of finite-difference time-domain (FDTD) method.

This paper discusses an optical filter designed using the two-dirnensional (2D) photonics crystal. The filter has been designed to work in Dense Wavelength Division Multiplexing (DWDM) cornrnunication using ultra cell resonant cavity. The filter analysis was initially carried out by changing the attributes of photonic crystal such as radius of inner ring rods and refractive index. Hence, it is possible to tune the wavelengths with characteristics according to DWDM standard. The filter is designed to work in 1552 nrn, 1553 nrn, 1554 nrn, 1555 nrn, 1556 nrn, 1557 nrn and 1558 nrn with Inrn channel spacing and 0.2 nrn spectral linewidth, 96 % to 100 % transmission efficiency, and quality factor to be 8000 respectively. The proposed filter was designed and sirnulated with Finite-Difference Tirne-Dornain (FDTD) algorithrns and the results are discussed at the end for the use in Photonic Integrated Circuits.
