| Abstract | Summary form only given. Parameteric oscillators are nonlinear resonators in which a coherent pump wave is converted into coherent 'signal' and 'idler' waves of different frequency, thus forming the basis for broadband tuneable sources and mixers. They have found widespread application in both microwave and optical frequency regions, as well as providing a 'quantum testbed' for some of the most profound demonstrations of non-classical photon states. The major stumbling block for optical parametric oscillators (OPOs) has been their inefficient optical nonlinearities, only recently improved by the introduction of patterned media such as periodically-poled lithium niobate. We report the first optical parametric oscillation of a microcavity (termed a /spl mu/OPO) which crucially depends on the exciton-photon-physics of a strongly, coupled semiconductor microcavity. When pumped by a CW near-infrared laser at a critical angle, the device coherently radiates signal and idler beams of different wavelength in different directions. Successful shrinking of the shortest previous OPO device by a factor of 10000 results from modifying the quantum properties of exciton-polaritons in a microcavity environment. Phase matched interactions are simultaneously -possible for the pump, signal and, idler photons due to the Coulomb interaction between electrons and holes in the semiconductor layers. |

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.
