AbstractIn this paper, Two Dimensional (2D) Photonic Crystal (PhC) based 3-input all optical NOR, NAND and XNOR gates is proposed and designed. The proposed device is formed by the combination of line defects and square cavity. The performance of the device is analyzed using 2D Finite Difference Time Domain (FDTD) method. The band gap analysis is done by Plane Wave Expansion (PWE) method. The device has the lattice constant and refractive index of 616 nm and 3.46, respectively. The dimension of the proposed structure is about 12.5 µm*12 µm which is highly compact and suitable for photonic integrated circuits (PIC).

The Impact

All-optical logic XNOR gate is realized by a series combination of XOR and INVERT gates. This Boolean function is realized by using Mach-Zehnder interferometers (MZIs) and exploiting the nonlinear effect of two-photon absorption (TPA) in semiconductor optical amplifiers (SOAs). The employed model takes into account the impact of amplified spontaneous emission (ASE), input pulse energy, pulsewidth, SOAs carrier lifetime, and linewidth enhancement factor (α-factor) on the gate’s output quality factor (Q-factor). The outcome of this study shows that the all-optical XNOR gate is indeed feasible with the proposed scheme at 250 Gb/s with both logical correctness and acceptable quality.

Difference Time

AbstractAll optical logic gates can play very important roles in all optical digital systems. In this paper we designed an all optical XNOR gate. The switching part of the designed XNOR consists of two nonlinear resonant cavities. The nonlinear cavities were created by adding two nonlinear defects made of doped glass. Plane wave expansion and finite difference time domain methods were used for simulating the designed structure. The final structure has two input and one output ports. The output port is ON when the input ports have similar states. For the designed structure the delay time is about 2.5 ps.
