Quaternary Bit-Swap Logic with QPSK Signal Using Four Wave Mixing

Abstract

Abstract Multilevel modulation formats have been now investigated very much to increase the speed and data capacity of optical communication networks in the limited bandwidth. Quadrature phase modulated signal has captured the attention of the researchers in this aim due to its high spectral efficiency and less bit error rate. Quaternary Bit-Swap logic operation is very important fundamental logic operation related to fast and secure computing and communication. Here in this report the authors propose a new method of implementation of all-optical quaternary Bit-Swap logic operation with quadrature phase modulated signal using four wave mixing.
