چکیده

In this paper we combined an optical mixer via photonic crystal ring
resonator to propose an all optical 1 to 2 decoder. The main idea used in this paper is
based on controlling the optical behavior of the resonant ring via optical power
intensity. We know that resonant wavelength of the photonic crystal ring resonator is
very sensitive upon the refractive index of dielectric rods, on the other had the refractive
index of dielectric materials depend on the optical power intensity. Therefore we can
change the resonant wavelength of the resonator by increasing the optical power
intensity up to adequate amount. The final structure has two output ports whose working
states can be controlled by one input port. When I is OFF, the O1 port will turn ON and
O2 is OFF, when I is ON, O1 turns OFF and O2 turns ON. The proposed structure works
completely in optical domain without any electronics.
