Abstract

An all-optical binary-coded decimal (BCD) adder with the help of Terahertz Optical Asymmetric Demultiplexer (TOAD) is proposed and described. The paper describes the all optical BCD adder by using a set of all-optical full-adder, optical beam combiner, and optical switch. In electronic computing systems, BCD is an encoding for decimal numbers in which each digit is represented by its own binary sequence. Its main virtue is that it allows easy conversion to decimal digits for printing or display and faster decimal calculations. Numerical simulations (by Mathlab6.5) result confirming described methods and conclusion are given in this paper.
