| Abstract | Monolithic integration of LD and LED transmitters operating at 100-400 Mbit/s is investigated using a 3-μm Si-bipolar process as a first step in the establishment of a master-slice IC technology for optical communication systems. An LD transmitter IC is developed as a master IC, which includes a differential current switch and an input buffer circuit for high-speed modulation and a current stabilizer and an APC circuit for the stabilization of the output optical power, An LED transmitter is fabricated by the minor change of wiring of the master IC. The former exhibits 0.5-ns rise and 0.7-ns fall times at the signal current of 40 mA. Also the latter exhibits 0.4-ns rise and 0.6-ns fall times at the signal current of 100 mA. Characteristics of LD and LED transmitters are estimated in order to prove the usefulness of the fabricated IC's. As a result, it is confirmed that both transmitters using the fabricated IC's operate at the modulation speed of 300-400 Mbit/s and output optical power fluctuations of less than ±0.5 dB over the ranges of 5V ±5 percent supply voltage and 0-50°C temperature. From these results, it is proven that the master-slice monolithic integration is feasible and will be very useful for reduction of the turn-around time in IC development. |

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.
