| Abstract | The influence of the spectral allocation of input channels on the dynamic response of three-level erbium-doped fiber amplifiers (EDFAs) governed by spectral hold burning (SHB) and site dependent pumping (SDP) is investigated, both, experimentally and theoretically. Using an experimental setup specifically designed to isolate and assess the SHB and SDP behavior we are able to validate, with a good accuracy, a mathematical model derived from the fundamental equations of the three-level amplifier. We conclude that by selecting a pump wavelength centered at 974 nm instead of 980 nm, we can reduce the power excursions by 23 %, and that by increasing the channel spacing from 100 GHz to 150 GHz the power excursions decrease by more than 20 %. Further simulations are done to investigate the behavior of SHB and SDP in an EDFA with ideal gain control. We verify that in a subband switch, changing from the red subband to the blue subband causes higher deviations than when changing from the blue subband to the red subband of the c-band. Also, in a drop scenario, the overshoots and undershoots of the surviving channel depend on the input channels spectral allocation and on the gain of the amplifier. |

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.
