| Abstract | We numerically analyze the stimulated Raman scattering (SRS) in nonlinear photonic crystal fibers (PCF). Generalized nonlinear Schrodinger equation was used to model the propagation of femtosecond pulses in PCF. We demonstrate that, for a sufficiently broad spectral content, stimulated Raman scattering transfers energy from the higher frequency spectral components to lower frequencies, resulting in a continuous self-frequency shift to longer wavelengths. The obtained results show that PCF can generate relatively strong SRS and that the higher the nonlinearity, the faster the speed of soliton fission, thus the greater the number of solitons produced at the same time. The important role of Raman scattering in the generation of a broad supercontinuum is pointed out. |

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.
