The present work introduces and explores, using the OptiSystem software, the performance of an optical system that combines the Mach-Zehnder interferometer, the semiconductor optical amplifier (SOA), and the Fiber Bragg Grating (FBG). The system is composed of three main parts: the transmission section, the semiconductor optical amplifier Mach-Zehnder interferometer (SOA-MZI) section, and the reception section. The performance parameters analyzed include the quality factor (Q-Factor) and the bit error rate (BER) for different bit sequences and variations in the optical fiber length. Overall, the proposed system demonstrated good performance, proving to be a viable design for metropolitan networks with links up to 50 km.

In this work, proposes all-optical logic gates device structure based on a Michelson interferometer (MI) composed of semiconductor optical amplifier (SOA) forming a structure of SOA-MI logic devices with symmetrically identical Fiber Bragg Grating (FBG) at the output of each of its arms, for numerical simulation of the all-optical AND, OR and NOR logic gates of two binary input signals with different bit numbers using the cross-gain modulation (XGM) technique at 10 Gb/s bit rate and filter bandwidth at 10, 20 and 40 GHz using OptiSystem 15.0 software by OptiWave Corporation, to demonstrate and extract simple design rules for high-speed optical processing and analysis of non-linear SOA-induced properties. In addition, this work includes the study of the effect of bandwidth and number of bits on received power, minimum bit error rate (BER), maximum quality factor (Q-factor), Optical Signal to Noise Ratio (OSNR) and optical spectrum, which demonstrates high-speed gates and performance. Were run the SOA-MI-based logic gates with some parameters and the results can demonstrate a structure of high-performance optical logic devices with high speed.
