| Abstract | For conventional passive alignment of optical fibers in optoelectronic packaging, the position of each optical fiber is defined by the geometry of a V-groove. The epoxy is dispensed from the top of the V-groove and another cover plate is usually required to press the fiber against the walls of the V-groove. In the present study, a new technique for epoxy dispensing is developed, where some low viscosity epoxy is dispensed in a "reservoir", flows into the V-groove, and then through the gap between the optical fiber and the V-groove walls. The excess epoxy is diverted to a "canal" next to the "reservoir". It is observed that the flow of epoxy can align the optical fiber by surface tension. Once the fiber is aligned and the epoxy is cured, more epoxy is applied in a glob-top manner for mechanical enhancement. A cover plate is not required. The configuration of the V-groove and associated features, the epoxy dispensing process, and the results of alignment are presented in detail. Experiments show that the optical fiber, which has more than 60 /spl mu/m initial misalignment, aligns with the centre of the V-grooves within 0.5 /spl mu/m. |

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.
