| Abstract | A probe that enables optical coupling to planar lightwave circuits (PLCs) is described. A flexible waveguide is used to form a variable length directional coupler that extracts light from a waveguide in the wafer to the probe. Varying the length enables optimal coupling to be achieved for a wide range of probe-to-waveguide gap, materials, widths and cladding thicknesses present on a chip. In this paper we consider the use of SU-8 polymer as waveguide test probe and polydimethylsiloxane (PDMS) as cladding for the probe. The results indicate that this approach is ideal for characterizing PLC's as the 3dB bandwidth of the probe covers the whole 1300 - 1700 nm fiber-optic telecommunication range. Coupling length control in the range of 50 - 200 mm leads to maximum coupling in excess of 80% for the range of conditions investigated. |

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.
