| Abstract | The recent progress in optical communications and signal processing outlines the fact that the parallel computing falls well behind the optical transmission systems' capabilities. Even though that photonic networks-on-chips (NOCs) can be employed to enable future computing and signal processing functions, there is a number of limitations (such as frequent O-E-O conversions, temperature sensitivity, and reliability issues) to be overcome before such schemes become widely adopted. All this strengthens the need for novel optical computing paradigms to be introduced. In this paper, we discuss novel optical processing schemes to overcome the computing limitations of photonic NOCs. We describe both continuous-time (CT) and discrete-time (DT) implementations of photonic integrated circuits (PIC)-based basic building blocks for all-optical computing. In addition, we need to use all-optical error correction schemes to deal with the accumulated errors due to the impact of noise. To perform all-optical linear block encoding and decoding we discuss and propose the use of SOA based XOR gates, while for CT implementation, the employment of Mach-Zehnder interferometer-based multiplier to perform probabilities multiplication, is considered. Also, the use of Y-junctions and phase modulators for all-optical FFT is discussed. Finally, we will describe and propose our approach of how to perform all-optical multiplication and addition in Galois field (GF), which represent the basic operations required in nonbinary LDPC coding and byte-based computing functions. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
