Abstract
The manuscript presents Design of All-optical AND logic gate at 20 Gb/s using Semiconductor Optical Amplifier based on Michelson Interferometer (SOA-MI). The paper shows a comprehensive numerical simulation using OptiSystem software to examine two-input logical function (with 8-bit). Used the CW Laser, Dual Directional Coupler, 100% reflective linear Fiber Bragg Grating (FBG) and Optical Filter, and investigated the optimum injection current and length of the TWA-SOA for obtaining the best result Q-Factor and BER based on Eye diagram to logic gate. To the best of our knowledge, this is the first report on a numerical simulation of an All-Optical AND logic gate at 20 Gb/s with SOA-MI using co-propagating, structure with results ensure good performance of the proposed design.
Highlights
In this paper, all-optical AND logic gate is simulated, mainly based on Michelson interferometer (MI) with semiconductor optical amplifier (SOA) and mechanism of copropagating semicondutor baseado no interferômetro de Michelson (SOA-MI) configuration along with non-linear property to design AND gate using OptiSystem software.The fiber optics are efficient and robust systems, essential that telecommunication systems at ultra-fast speeds with high bit rate, and the Semiconductor Optical Amplifiers (SOA) ensures high data rates, direct amplification of optical signals and energy efficiency, omit the need of converting the signal from optical to electric and vice versa [1].Optical Amplifiers are designed to omit the need of converting the signal from optical to electrical and again to optical, and direct amplification of optical signals is done by the amplifier [1]
The paper is organized as follows: in section II we present the SOA-MI design of AND logic gate, in section III the results and discussions of the simulations and in section IV the conclusions, acknowledgments and references
In optical fibers the configuration of the Michelson interferometer can be obtained from the cascade association of two optical components: a directional coupler and 100% reflective linear Fiber Bragg Grating (FBG) [7]
Summary
All-optical AND logic gate is simulated, mainly based on Michelson interferometer (MI) with semiconductor optical amplifier (SOA) and mechanism of copropagating SOA-MI configuration along with non-linear property to design AND gate using OptiSystem software. The fiber optics are efficient and robust systems, essential that telecommunication systems at ultra-fast speeds with high bit rate, and the Semiconductor Optical Amplifiers (SOA) ensures high data rates, direct amplification of optical signals and energy efficiency, omit the need of converting the signal from optical to electric and vice versa [1]. Since the carrier density change in SOAs will affect all input signals, a signal at one wavelength can affect the gain of a signal at another wavelength [4] Among these approaches, SOA is believed to be a key component, useful building blocks for all-optical gates, because it has the stronger gain nonlinearity characteristics than optical fibers and is easier for integration used to design the all-optical gates [5, 6]. The paper is organized as follows: in section II we present the SOA-MI design of AND logic gate, in section III the results and discussions of the simulations and in section IV the conclusions, acknowledgments and references
