All-Optical Quaternary Logic Based Information Processing: Challenges and Opportunities

چکیده
Science and Technology is providing people all over the world with much better ways of communicating than ever before, and the winds of change have whipped up the de‐ sire to exchange more of everything from messages to movies. The field of computation and signal processing is growing day by day [1-7]. In last three to four decades, the phi‐ losophy, science and technical prospects enriched the scientific communities a lot. Mas‐ sive parallelism, speed of operation, increased spatial density attracts in many ways the scientists, researchers and technologists. Very Large Scale Integration (VLSI) technology has revolutionized the electronics industry and established the 20th century as the com‐ puter age. But, VLSI technology is approaching its fundamental limits in the sub-micron miniaturization process. Therefore an alternative technological solution to the problem of high speed information processing is needed, and unless we gear our thoughts toward a totally different pathway, we will not be able to further improve our information proc‐ essing performance for the future. Conservative and reversible logic gates are widely known to be compatible with revolutionary computing paradigms. At the same time the Multi-valued logic (MVL) is also positioned as a coming generation technology that can execute arithmetic functions faster and with less interconnect than binary logic [8-48].

This paper presents a novel design of quaternary logic gates using graphene nanoribbon field effect transistors (GNRFETs). GNRFETs are the alternative devices for digital circuit design due to their superior carrier-transport properties and potential for large-scale processing. In addition, Multiple-valued logic (MVL) is a promising alternative to the conventional binary logic design. Sa...
متن کاملInterferometric switch based all optical scheme for conversion of binary number to its quaternary-signed digit form
Multi-valued logic (with radix. 2) can be viewed as an alternative approach to solve many problems in transmission, storage and processing of large amount of information in digital signal processing. In arithmetical operation signed digit number is very essential for carry free computation. To achieve the parallelism in computation, a suitable number system and an efficient encoding/decoding sc...
