| Abstract | The concept of wavelength division multiplexing (WDM) has revolutionized the field of optical communications. However, the immense demand for bandwidth shows no sign of abating and is pushing service providers to deploy communication networks with increased capacity. Optical transport networks will soon require channel data rates in excess of 100 Gb/s in order to continue to meet the ever increasing demand for bandwidth. Bandwidth flexible optical networks, that dynamically adjust transmission parameters and allocate the bandwidth according to the traffic demands, have been proposed in the literature to support 400 Gb/s and 1 Tb/s super channels [1]. In such systems, techniques including coherent optical OFDM and Nyquist WDM transmission [2] may be employed to achieve channel spacing at or close to the symbol rate. These high capacity transmission systems are well served by optical frequency comb (OFC) sources that can enable the reduction or elimination of guard bands by featuring fixed frequency spacing between the carriers, in contrast to arrays of independent lasers that do not. Moreover, an OFC that offers wavelength and free spectral range (FSR) tunability allows a single source to be easily adapted. Hence, in order to be successfully employed in such flexible systems, OFC sources should exhibit good spectral flatness, high frequency stability, low linewidth, and reconfigurable central wavelength and FSR. In this work, the authors present a reconfigurable gain switched optical frequency comb [3–5] and demonstrate its optimum features. In addition, several applications of this comb will be reviewed [6, 7]. |

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.
