Abstract
The research is centred on the optical implementation of an XOR/X-NOR gate at an ultra-fast speed of 200 Gb/s by employing the nonlinearity optimization approach. This system is optimized by adjusting the optical gain and phase shift of the SOA-MZI structure to modify the output pulses to match the necessary functioning of an all-optical XOR/XNOR gate at 200 Gb/s. All-optical XOR/X-NOR gates are developed by connecting semiconductor optical amplifiers (SOA) in the Mach–Zehnder Interferometer (MZI) structure. The results show that using a Delayed Interferometer in conjunction with the SOA-MZI increases the quality of the produced logic at the intended data rate of 200 Gb/s.
