| Abstract | This paper describes the development of a transmitter and receiver leveraging a combination of monolithic and hybrid integration for Datacenter applications to deliver 500Gbps over 2km on a single mode fiber. The transmitter encompasses 12 electro-absorptive modulated lasers (EMLs) with wavelength channels from 1270nm to 1380nm on a 10nm channel grid. The lasers are grouped in three (3) arrays with each array monolithically integrating four (4) EMLs operating at 43Gbps each. The three EML arrays are flip-chip bonded to a planar light-guide circuit (PLC), which serves as the mounting platform and provides the optical multiplexer function. The receiver couples the signal through an optical PLC-based de-multiplexer to twelve (12) high-speed PIN detectors with a 3dB bandwidth of more than 50GHz. The transmission tests were performed over 2km of SMF with each channel tested at 40Gbps. For the demonstration, a commercial semiconductor optical amplifier was used in front of the receiver to boost the signal. Each channel was tested to be error free to $<10^{−11}$ BER with most $<10^{−12}$ BER. The total cross-talk was measured to be between 1 and 2dB. The channel spacing of 10nm was chosen to enable a low cost transmitter operation without using Thermo-Electric-Coolers (TEC) in order to reduce the overall power dissipation. Instead of a TEC, resistive heating can be used to limit the temperature excursions and to enable an operating range of the TOSA from −5 to +75 deg C. This technology demonstration is a step towards the final goal of 1 Terabit/s transmission for Datacenter applications. |

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.
