All-optical 4-bit data comparator with the help of non-linear material based tree net architecture

Tree architecture and nonlinear materials have already taken a significant role in the field of optical interconnecting network and super fast photonic computing system. In this paper, an all-optical binary data comparison scheme is proposed and described with the help of nonlinear material based tree architecture. For any computing system it is very essential to know whether a binary number is greater than, equal to, or less than another binary number. So the role of comparison schemes is very important in data computing system.
