| Abstract | This paper reviews a new packaging technique for laser diode (LD) arrays. This technique uses a new film carrier which has high-density inner leads and fanned-out microstrip line patterns on polyimide film. The film carrier is used to connect the LD array to peripheral circuits, such as LD drivers. There is less mutual inductance between lines on the film carrier than with the conventionally used airing structure which comprises bonding wire and an alumina (Al/sub 2/O/sub 3/) circuit board. This structure can reduce the electrical crosstalk between channels on the LD array with high-density interconnection. A 4-channel LD array sub-module is fabricated employing the above technique, and demonstrated. The module has good frequency characteristics over a bandwidth of 2.3 GHz. The electrical crosstalk between adjacent LDs is less than -30 dB at 1 GHz. This value is about 10 dB lower than with the conventional wiring structure.< |

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.
