Abstract: (6332 Views)
In this paper we proposed an all-optical 3-Input NOR gate based on photonic crystals. In designing this gate we used three resonant rings. By employing the lattice constant of 625 nm, radius to lattice constant ratio equal to 0.265 and effective refractive index of 3.1, a fundamental crystal was obtained which is suitable for application in 1550 nm wavelength. By employing high intensity optical power into the device, based on Kerr effect the refractive index of the rods will be varied and the coupling of light into output will be controlled. The consistency of simulation results with the logical table of NOR gate confirms the suitable functionality of the device.
