Design and analysis of all-optical XOR gate using SOA-based Mach-Zehnder interferometer

摘要

The performance of ultra-fast all-optical XOR gate using two types semiconductor optical amplifier-based Mach-Zehnder interferometers (SOA-MZIs) is analyzed. Key parameters are optimized through numerical simulations. With properly designed parameters, 40 Gb/s all-optical XOR gate using SOA-MZI can be realized with fairly high performance. The results are helpful for parameter design of SOA-MZI-based XOR gate.
