| Abstract | We have developed ultralow-cost optical transceiver modules based on leadframe (LF) based plastic package. The vertical-cavity surface-emitting laser (VCSEL) based transmitter shows stable optical power output with a variation of less than 0.2dB over a wide temperature range from -40degC to +105degC. Optical output eye-diagrams at 50Mbps show excellent timing performance with low jittering less than 150ps. The extinction ratio is maintained around 8dB from -40degC to +105degC. The transmitter modules show excellent reliability data including 1000 cycles of temperature cycling from -40degC to +125degC. On the receiver side, we have fabricated GaAs metal-semiconductor-metal photo detectors (MSM-PD). The MSM-PD has a lower capacitance per unit area compared to conventional pin-photodiodes. The capacitance of the MSM-PD with diameter 250mum at different bias voltages is around 0.8pF at bias voltages from 0.5V to 10V. The MSM-PD receiver shows a wide open eye diagram at 3.2Gbps. From the bit error rate curve of the receiver we interpolate a sensitivity of better than -18dBm for error rate of $10^{-12}.$ We have demonstrated high speed transmission at 1.25Gbps over 10m PCS fiber with our VCSEL transmitter and MSM-PD receiver. For lower data rates and extended reach applications in low cost POF systems, we have developed Green-LED transmitters operating at 520nm wavelength. For a 40m POF system we obtain a 3.1dB wider power budget margin over the operating temperature range from 0degC to 85degC compared the red LED transmitters. The 10Mbps optical output waveforms are wide open at 25degC and 85degC |

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.
