In the recent years reversible logic design has promising applications in low power computing, optical computing, quantum computing. VLSI design mainly concentrates on low power logic circuit design. In the present scenario researchers have made implementations of reversible logic gates in optical domain for its low energy consumption and high speed. This study is all about designing a reversib...

Two-dimensional reversible cellular automata constructions may have utility for modeling problems that entail inherently reversible processes, such as optical propagation. This paper speculates on the potential of methods articulated in A New Kind of Science [1] for addressing inverse problems in optical scatterometry, and then describes preliminary work for two-dimensional reversible cellular ...

reversible logic circuits have found emerging attentions in nanotechnology,optical computing, quantum computing and low power design. a programmablelogic array (pla) is a universal circuit which is used to implement combinationallogic circuits. the main part of a pla is its and array. in this study we propose twotypes of optimized reversible programmable logic array (rpla) circuits. the firstty...

Considering the benefits of Quantum and Optics, if the logic gates in the quantum field and electronic structure are implemented using optical elements, then it will be benefited from advantages of Quantum and design, and these processing circuits can be used in optical computing and quantum computing, genetic processes, and other useful nanotechnology applications. In this study, we have intro...

The ultimate surface exposure provided by graphene monolayer makes it the ideal sensor platform but also exposes its intrinsic properties to any environmental perturbations. In this work, we demonstrate that the charge carrier density of graphene exfoliated on a SiO2/Si substrate can be finely and reversibly tuned between hole and electron doping with visible photons. This photo-induced doping ...

This paper describes the design of a novel CMOS binary fulladder structure which incorporates four-valued signalling internally. A biased CMOS pseudo-lineaadder provides a quaternary signal representing the number of ones in the three binary inputs. Three area-ratioed CMOS inverters interpret this to provide three binary signals which, combined in conventional static CMOS logic, generate the su...

Fabricating an electrically switchable cylindrical Fresnel lens based on holographic polymer-dispersed liquid crystals (H-PDLC) using a Michelson interferometer is reported. Simplicity of the method and possibility of fabricating different focal length lenses in a single set up are among the advantages of the method. It is demonstrated that the Fresnel structured zone plate acts as a cylindrica...
