In this paper an ultra-compact all-optical encoder is presented by using a two-dimensional photonic crystal. The designed logic gate is based on the interference effect. The proposed structure consists of several photonic crystal waveguides connected by 2 nano-resonators. The nano-resonators are designed to reduce the size of the radius of the dielectric rods. The contrast ratios and delay time for the proposed all-optical encoder are respectively 6 dB and 125 fs. The size of the structure is equal to 132 µm2. Equality of the output power in the logic states “one”, the small dimensions, the low delay time, compact and simple structure have shown that the logic gate is suitable for the using in optical integrated circuits.

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.

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.

Ring Core

Abstract Transmission efficiency, quality factor, crosstalk levels and number of output channels are the most crucial parameters in designing optical demultiplexers, suitable for wavelength division multiplexing applications. In this paper we proposed an 8-channel optical demultiplexer based on photonic crystal ring resonator. For performing wavelength selection task we used eight ring resonators. The resonance wavelength of the ring resonators depends on the dimensions of the ring core, therefore we choose eight different values for the lattice constant of the ring resonators core section. The average channel spacing of the structure is about 3 nm the transmission efficiency in most of the channels is equal or more than 99 % except in one channels whose transmission efficiency is 85 %.
