| Abstract | Monolithic arrays of optical switches based on the integration of GaAs vertical cavity surface-emitting lasers (VCSELs) with heterojunction phototransistors form a flexible two-dimensional switching fabric that is useful for a variety of applications in parallel optical processing. VCSEL-based optical switches with high optical gain and contrast can perform digital logic as well as amplification and memory functions, while binary switch nodes can spatially re-route the optical signal paths at high speed in a multi-stage optical switching network. These switches can also be integrated with heterojunction bipolar transistors (HBT) to form a high speed (GB/s) electrical-to-optical (O-to-E or E-to-O) interface to VLSI electronics, thus providing simple communication between the optical switching network and the electronic control and processing functions. We describe below the first monolithic demonstration of an optoelectronic switch integrating an HBT with a VCSEL, achieving low modulation current, high current gain, and efficient electrical-to-optica1 conversion. |

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.
