The implanting of optical routers in telecommunication optical network necessitates the modeling constituent’s amounts and approvals which encircle the considered router. For it, in this work, we investigate three types of filters with base 2D photonic crystals. The first, it is a narrow band optical filter, this system is constituted with two waves guides obtained by omitting one row of holes of the photonic crystal, coupled among them by a resonant cavity formed by a point of defect in the crystal. Near the resonant frequency (??a/2πc = 0.38), light from the input waveguide can couple into the cavity, and the cavity in turn can couple into the output waveguide, is that the peak transmission is precisely 100%.Then a Band Pass Filter is proposed, the out put transmission spectra of our filter covered three band. Band I covers the wavelength range from 1.331 to 1.355 μm has 86% of transmission power, Band II, from 1.390 to 1.427 μm, has 98% of the transmission power and Band III from 1.46 to 1.507 μm, and has 27% of the transmission power. The full width at half maximum bandwidth of these bands is 9.7, 13.1 and 16.4 nm,respectively. And finally a new constitution of “Channel Drop Filter " is simulated, it consists of two waveguides bends coupled among them by linear resonant cavity. The power dropped from the input waveguide bend into the drop channel at 1550 nm (the resonant frequency)is about 89%; the power transferred to the other channels is less than 5%. The Band of out put transmission spectra of the drop channel cover the wavelength range from 1505 to 1600 nm and the bandwidth is about 12.7 nm and the Q factor is 122.
The temporal and spectral behavior of the device is studied using two dimensional Finite Difference Time Domain Method (2D-FDTD) and Plane Wave Expansion (PWE) methods respectively. |
