Abstract | A comprehensive broad-band dynamic model of a tunable wavelength converter based on four-wave mixing (FWM) in a semiconductor fiber ring laser (SFRL) is presented. Critical factors, e.g., the material gain profile, the longitudinal variation of the optical field, the carrier density, photon density, and the broad-band spontaneous noise emission, are considered in the model. Therefore, the static and dynamic characteristics of this kind of wavelength converter can be predicted more accurately. By numerical simulation, the effects of the input signal power, injection current, the coupling coefficient of the output coupler, and the lasing wavelength on the conversion efficiency of the wavelength converter are investigated. Also, the optical pulse pattern, frequency chirp, and extinction ratio of the conjugate signal are evaluated. To widen the dynamic range of input signal power, an erbium-doped fiber amplifier (EDFA) is added into the SFRL. The characteristics of this tunable wavelength converter with an SFRL are investigated in detail. |

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.
