All-optical binary flip-flop with the help of Terahertz Optical Asymmetric Demultiplexer

Abstract

The memory device is very important as they store various values either temporary or permanently. Optical flip-flop memories form a fundamental building block for all-optical packet switches in the next generation communication networks. All-optical flip-flop memory with the help of Terahertz Optical Asymmetric Demultiplexer (TOAD) is proposed and described. Principles and possibilities of all-optical circuits for TOAD based S-R, J-K, D and T flip-flop are reported. Numerical simulation confirming described method is also given in this paper.[PUBLICATION ABSTRACT]
