Abstract
Abstract
The optical components based on photonic crystal had a wide range of applications fields these last years. In this work, we propose a configuration of photonic crystal structure of Channel Drop Filter (CDF). The proposed filter study by finite difference numerical method in the time domain FDTD makes it possible to ensure an average detected modal transmission rate of 95.30%, an average quality factor of order 3149.12 and a compact size of 144.65 μm2 with high sensitivity to small variation of refractive index, period and radius of rods. Thus, we designed demultiplexer with four channels, which has a low average crosstalk of −30.73 dB. The transmission and the quality factor are 90.94% and 2221.13 respectively, with channel spacing 4.2 nm and a size of 405.6 μm2. These properties make our model of the proposed filter and demultiplexer well adapted for the realization of optical integrated circuit.
