| Abstract | A new germanium sulphide glass has been synthesised as host material for praseodymium (Pr/sup +3/) doped 1.3 /spl mu/m fibre amplifiers. The low phonon energy of germanium sulphide glasses makes them ideal candidates as host material for high-efficiency fibre amplifier devices. /sup 1/G/sub 4/-/sup 3/H/sub 5/ spontaneous emission spectrum and /sup 1/G/sub 4/ fluorescence lifetime were measured in selected Pr/sup +3/-doped glass compositions and a quantum efficiency of 60% was calculated. Input data for fibre amplifier numerical modelling were provided by the optical characterization of Pr/sup +3/-doped glass samples. Incoherent signal contribution to the signal amplification process, such as amplified spontaneous emission (ASE), is also considered in order to design high efficiency low noise fibre amplifiers. In the small-signal regime a pump-gain conversion efficiency equal to 0.65 dB/mW was calculated, pointing out the efficiency of the designed fibre amplifier to convert the optical pump power into available signal gain. |

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.
