All-Optical Approach for Conversion of a Binary Number Having a Fractional Part to Its Decimal Equivalent and Vice-Versa

Abstract

Optics is found as a very potential candidate in information processing and computing. Several all optical methods have been proposed for implementation of all optical logic and arithmetic devices during the last few decades. In this regard, the role of optical tree architecture can be mentioned as an important approach for conversion of an optical data from binary to decimal and vice-versa. In this communication, the authors propose a new concept of conversion of a binary number having some fraction (fractional value) to its equivalent decimal counterpart and its vice-versa. To perform this operation, optical tree and some nonlinear material based switches are used properly.
