| Abstract | Multistate self-electrooptic-effect devices (M-SEEDs) containing several quantum-well diodes in series are discussed. It is shown that a device with N diodes in series with a voltage source and illuminated by N diodes in series with a voltage source and illuminated by N light beams has N stable states corresponding to any one (and only one) of the diodes being highly transmissive. This voltage-biased M-SEED can perform contention resolution in the sense required by analog systems, because the diode illuminated by the weakest beam becomes the highly transmitting one on powering up the system. A current-biased M-SEED with N diodes in series with a current supply can have 2/sup N/ stable states, corresponding to any combination of diodes in their transmitting or absorbing states. This same device can also function as a binary image thresholder. The M-SEEDs are multistable in multiple beams, in contrast to previous multistable optical devices that have multiple states for one beam. Electrically and optically enabled symmetric SEEDs (S-SEEDs) that comprise a pair of quantum-well p-i-n diodes in series with a transistor or a third diode are also discussed. This device is the equivalent of an electrical tristate device that is used in some bus architectures.< |

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.
