Optimization of All-Optical Logic Gates Based on HNLF-MZI and Phase Shifter Configuration

All-optical processing (AOP) is an imminent technology and has great demands in optical computing and optical networks due to ultra-fast operations. Optical logic gates (OLGs) are building blocks of all-optical flip flops, counters, and memories and have been investigated relentlessly in previous studies incorporating semiconductor optical amplifiers (SOAs), optical filters, dispersion compensations fibers (DCFs), Mach–Zehnder interferometer (MZI), Sagnac interferometer, etc. The high speed and reliability of existing OLGs are limited in the techniques mentioned above. Therefore, in the present study, we demonstrate a 180 Gbps ultra-high speed reconfigurable and scalable NOT, AND, and XOR gates using highly nonlinear fibers (HNLFs) in the MZI configuration and a phase shifter. The principle of proposed OLGs is cross-phase modulation (XPM) and self-phase modulation (SPM) in HNLF. Single parameter optimization (SPO) in Optisystem is explored to find optimal parameters of HNLF, rectangle bandpass filters, light sources, and photodetectors.
