Original architecture of an efficient all-optical 2 × 4 photonic crystals decoder based on nonlinear ring resonators

In this paper, we have presented an efficient original architecture of all-optical 2 × 4 photonic crystal decoder based on non-linear ring resonators. The fundamental structure is a square lattice 2D GaAs rods, operating around the wavelength 1.55 µm. proposed composed combiner with three input ports, where port E used for excitation and A1, A2 are control optical switch four output it nonlinear DMEX. For creation at µm, chalcogenide glass rods Kerr coefficient equal to 9 10–17 m2/w. switching intensity size 1 Kw/µm2, 27.12 µm 17.96 respectively. contrast ratio about 8.7. maximum crosstalk insertion losses calculated be ? 22.1 4.5 dB. minimum power levels logic states 0 0.05 P0 0.37 power. finite element method was perform necessary calculations.
