Abstract

In this paper, the design and performance of two dimensional (2-D) photonic crystal (PhC) coarse wavelength division (de)multiplexer is investigated using finite difference time domain (FDTD) method. The photonic band gap (PBG) is calculated by plane wave expansion (PWE) method. The proposed design provides two de-multiplexed central wavelengths one at 1551nm and another at 1591nm which belong to the most popular ITU-T G.694.2 CWDM grid wavelengths range in optical communication system. The calculated quality factors for the two wavelengths 1551nm and 1591nm are around 346 and 272 respectively. The de-multiplexer is designed by two dimensional photonic crystals having 40×35 dielectric rods of dielectric constant 3.49 suspended in the air background. This de-multiplexer may be used as a key component in optical integrated circuits and optical network applications. The device is ultra-compact with overall size of the wafer around 24 µm × 21 µm.
