| Abstract | Two selected applications of semiconductor optical amplifiers (SOA) are discussed, namely linear in-line amplification in gigabit passive optical networks and fast nonlinear all-optical signal processing. We report on measurements demonstrating the suitability of quantum-dot (QD) and bulk SOA for the respective application areas. For in-line amplification the saturation power of the SOA should be large, while it has to be low for efficient signal processing. For bulk SOA we find by physically-based simulations that at large injection currents and for a fixed gain, p-doping (n-doping) of the active layer increases (decreases) the saturation power. Recently published experiments show that qualitatively these results carry over to QD-SOA. |

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.
