Optical half subtractors are required for designing any optical computation system. Operation speed and the on/off contrast ratios very important characteristics logic device. A novel structure composed of three nonlinear ring resonators some waveguides used proposed subtractor with improved operation ratio. The simulation results show that rise time this is 1.5 ps. Also B D 13.7 dB 14.5 respec...

By exploiting the phenomena of optical switching, different logical and arithmetic operations can be performed. This paper presents a novel optimized design structures to perform addition subtraction two binary digits using electro-optic effect based Mach–Zehnder interferometer operating at 1460 nm in S band. The proposed are numerically simulated designed beam propagation method MATLAB softwar...

In present day skill, designing of low power systems has emerged as one of the vital theme of electronic industries due to the point that, power consumption is drawing much of the absorption in any very large scale integration (VLSI) chip design. Design of low power circuit for high performance is the necessary main concern of VLSI technique. This paper presents designing of Half Subtractor usi...

Diverse advanced logic circuits are fabricated to implement arithmetic functions based on a simple and single molecular beacon platform, including half adder, half subtractor, full adder, full subtractor, and a digital comparator. Dual fluorescence outputs are generated in parallel and a constant threshold value is set to build all the logic circuits. The developed enzyme-free DNA system provid...

Abstract: In this paper, we aim to design and propose a novel structure for all-opticalhalf subtractor based on the photonic crystal. The structure includes two optical switches,one power splitter, and one power combiner. The optical switches are made of theresonant rings which use the nonlinear rods for dropping operation. The footprint of thedesigned structure is about...

Quantum computers require quantum processors. An important part of the processor of any computer is the arithmetic unit, which performs binary addition, subtraction, division and multiplication, however multiplication can be performed using repeated addition, while division can be performed using repeated subtraction. In this paper we present two designs using the reversible R gate to perform t...

The ionic inputs to new fluorophore have been mimicked as a superimposed electronic molecular keypad lock and half-subtractor.
