Analysis of All-Optical XNOR Gate in SOA Based Tree-Net Architecture

In this communication, we are going to design a new all-optical SOA based XNOR gate using tree architecture implementing the cross-polarization modulation (XPolM) effect in semiconductor optical amplifier (SOA). We get some good values related to quality factor (Q~62 dB) and some other performance-related parameters associated with a very high speed (~100Gbit/s) of operation.
