| Abstract | We experimentally demonstrate the influence of a high power continuous wave (CW) injection, as a holding beam (HB), into an SOA around the gain transparency wavelength on the bit error rate (BER) of a signal modulated at 2.5 Gb/s traveling through the amplifier. We show that the injection of an HB power of 19 dBm at 1480 nm inside an SOA, in three regimes (absorption, transparency and gain), can reduce the signal BER, mainly, when working at high input signal powers. As a result for a BER of $10^{-9},$ an improvement more than 2.5 dB of input power can be obtained following the HB regime injection. In addition, we use the HB injection in an SOA based multi-channel WDM transmission system to reduce the crosstalk penalty between signals, which is caused by the cross-gain modulation (XGM). Experiment shows that the crosstalk penalty between two signals is suppressed and the SOA induced BER is improved when injecting the HB in the absorption regime. However, this penalty is noticeably reduced by the HB injection in the two other regimes |

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.
