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...
The IST-LASAGNE project aims at designing and implementing the first, modular, scalable and truly alloptical photonic router capable of operating at 40 Gb/s. The main results achieved in the project are presented in this paper, with emphasis on the implementation of network node functionalities employing optical logic gates and optical flip-flops, as well as an economical study on the proposed ...
• A submitted manuscript is the author's version of the article upon submission and before peer-review. There can be important differences between the submitted version and the official published version of record. People interested in the research are advised to contact the author for the final version of the publication, or visit the DOI to the publisher's website. • The final author version ...
A simple all-optical logic device, composed of an SOA and an optical filter, is proposed. By utilizing optical filtering, multi-logic functions (AND, OR and XOR) are demonstrated at 10 Gb/s using the same setup, under different operation conditions. Simulations indicate that the device can operate at much higher bit rate. Introduction: All-optical logic gates have received considerable attentio...
We present some compact quantum circuits for a deterministic quantum computing on electron-spin qubits assisted by quantum dots inside single-side optical microcavities, including the CNOT, Toffoli, and Fredkin gates. They are constructed by exploiting the giant optical Faraday rotation induced by a single-electron spin in a quantum dot inside a single-side optical microcavity as a result of ca...
This study introduces a reversible optical fulladder. Also optical NOT and NOR gates are implemented through Electro-Absorption-Modulator / Photo Detector (EAM/PD) pairs, were utilized for fulfilling reversible R gate. Then, reversible fulladder was designed based on the proposed reversible optical R gate. The operation of the suggested fulladder was simulated using Optispice and it was fou...
