All optical ۱ to ۲ decoder based on photonic crystal ring resonator

In this paper we combined an optical mixer via photonic crystal ringresonator to propose an all optical ۱ to ۲ decoder. The main idea used in this paper isbased on controlling the optical behavior of the resonant ring via optical powerintensity. We know that resonant wavelength of the photonic crystal ring resonator isvery sensitive upon the refractive index of dielectric rods, on the other had the refractiveindex of dielectric materials depend on the optical power intensity. Therefore we canchange the resonant wavelength of the resonator by increasing the optical powerintensity up to adequate amount. The final structure has two output ports whose workingstates can be controlled by one input port. When I is OFF, the O۱ port will turn ON andO۲ is OFF, when I is ON, O۱ turns OFF and O۲ turns ON. The proposed structure workscompletely in optical domain without any electronics.
