|Abstract||Moore's Law has set great expectations that the performance of information technology will improve exponentially until at least the end of this decade. Although the physics of silicon transistors alone might allow these expectations to be met, the physics of the long metal wires that cross and connect packages almost certainly will not. Global-level interconnects incorporating large-scale integrated photonics fabricated on the same platform as silicon microelectronics hold the promise of revolutionizing computing by enabling parallel many-core and network switch architectures that combine unprecedented performance and ease of use with affordable power consumption. Over the last decade, remarkable progress has been made in research on low-power silicon photonic devices for interconnect applications, and CMOS-compatible fabrication technologies promise a “Moore's Law for photonics” that could completely change the economics of integrated optics. In this survey, photonic technologies amenable to large-scale CMOS integration are reviewed from the perspective of high-performance interconnects operating over distance scales of 1mm to 100m. An overview of the requirements placed on integrated optical devices by a variety of modern computer applications leads to discussions of active and passive photonic components designed to generate, guide, filter, modulate, and detect light in the telecommunication bands. Critical challenges and prospects for large-scale integration are evaluated with an emphasis on silicon-on-insulator as a platform for photonics.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
