| Abstract | Summary form only given. Segmented semiconductor optical amplifiers (SSOA) have been shown to be a promising candidate for header generation and recognition. Unfortunately, the low modulation depths in these experiments required signal averaging to reduce the noise floor below the output signal. In this presentation a SSOA with asymmetric segment lengths is used in conjunction with a pattern repetition rate of 500 MHz to increase the modulation depth beyond previous work. Pump-probe experiments conducted without signal averaging demonstrate an adequate signal-to-noise ratio that makes possible single shot optical correlation at 100 Gbit/s. Since gain and loss operate together to give the SSOA functionality it important to understand the gain and loss dynamics to achieve optimum performance such as maximizing the modulation depth of positive and negative bits and balancing the recovery time of the saturated gain and the saturated loss. The presentation addresses these issues in addition to the effects of wavelength on the picosecond time-scale operation of the device. |

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.
