Universal Gate

AbstractOptical NAND gate is a universal gate which can be used for implementing different kinds of combinational circuits without using other gates. Due to significance of optical NAND gates in the optical communications, in this paper we proposed a novel structure for designing an all optical NAND gate based on photonic crystal structures. The proposed structure was designed using threshold switching mechanism which can be implemented using nonlinear ring resonators. In the proposed structure delay time is about 2.3 ps.

AbstractIn this paper we proposed a new design for all-optical NAND gate. By combining nonlinear Kerr effect with photonic crystal ring resonators first we designed a structure, whose optical behavior can be controlled via input power intensity. The switching power threshold obtained for this structure equal to 1 kW/μm

Abstract Increasing the speed of operation in all optical signal processing is very important. For reaching this goal one needs high speed optical devices. Optical half adders are one of the important building blocks required in optical processing. In this paper an optical half adder was proposed by combining nonlinear photonic crystal ring resonators with optical waveguides. Finite difference time domain method wase used for simulating the final structure. The simulation results confirmed that the rise time for the proposed structure is about 1 ps.
