Analysis of All-Optical XNOR Gate Using Quantum Dot Semiconductor Optical Amplifier (QDSOA)

All optical Majority gate using Quantum dot SOA based Tera hertz Optical Asymmetric Demultiplexer (TOAD)

“…In the work by Han, Huining, et al [25], QDSOA based TOAD is utilized to implement wavelength conversion at 160 Gb/s. In [26], Mukherjee, K has analyzed QDSOA based TOAD as an optical switch and recently different high speed logic devices [27][28][29][30] use this QDSOA based TOAD as optical switch shows 1Tb/s operating speed. This includes digital to analog converter (DAC) [27], artificial optical neuron [28], XOR gate [29], and XNOR gate [30].…”

“…Extinction ratio(ER), Contrast ratio (CR), Amplitude modulation (AM), Quality factor (Q) and relative eye opening (REO) are calculated, optimized for control power and their dependence on the amplified spontaneous emission (ASE) noise is investigated. The rest of the paper is organized as: Mathematical analysis of QDSOA based TOAD Design and working of the QDSOA TOAD based majority gate Simulation results and discussions Conclusions Mathematical analysis of QDSOA based TOAD: The detail analysis of the QDSOA based TOAD is described in [25][26][27][28][29][30][31]. Figure 1 shows the basic structure of the TOAD with QDSOA.…”

“…The gains of the QDSOA are calculated using the rate equation model described in the works [26][27][28][29][30]. Equations ( 1) and ( 2) along with the four coupled equation ( 3) to (6) given below are numerically simulated using fourth order Runge -Kutta method as described in [31].…”
