| Abstract | The design and the spectral gain and noise figure (NF) characteristics of tellurite-based fiber Raman amplifiers (FRAs), which are tellurite FRAs (T-FRAs) or hybrid tellurite/silica FRAs (hybrid FRAs), are described. Propagation equations for a multiwavelength (multi-/spl lambda/)-pumped T-FRA that include the pump interaction terms are presented, with which the gain and NF of the T-FRA can be calculated. Tellurite fiber (TF) length dependences of gain and NF of a T-FRA are clarified experimentally and theoretically. Numerical calculations on the gain and NF spectra of the tellurite-based FRAs show that a T-FRA with a two-stage configuration and a hybrid FRA with a three-stage configuration can provide seamless gain bands with widths of more than 130 nm over the S-, C-, and L-bands. The two-stage T-FRA has a couple of two-/spl lambda/-pumped T-FRA stages, and a gain equalizer (GEQ) and a dispersion-compensation fiber (DCF) between the T-FRA stages, while the three-stage hybrid FRA has a couple of two-/spl lambda/-pumped T-FRA stages, and a GEQ and a two-/spl lambda/-pumped DCF Raman amplifier (DCF-RA) stage between the T-FRA stages. The numerical calculations also show that the two-stage T-FRA and the three-stage hybrid FRA achieve top gains with regard to their flattened gain spectra of 9.7 and 24 dB, and maximum NFs in their gain bands of 11.8 and 8.2 dB, respectively. Measured gain and NF spectra of the tellurite-based FRAs coincide well with the corresponding calculated spectra. |

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.
