Summary on Grant Application Form
The current explosion in optical communications has been most dramatic in the field of optical datacommunications where channel bandwidths have recently been increasing by a factor of 10 every 2-3 years. For instance the 10 GbE standard is likely to be confirmed in 2001 and at that time most of the major components manufacturers will have a 10Gb/s transceiver solution available. It is likely that the next generation component will be a 40Gb/s transceiver. This project will seek to develop the major component parts of such a transceiver and develop a pre-production prototype. A major part of the work will be to develop the low cost, uncooled optical transmitter. Whilst directly driven lasers will be studied, they are not likely to deliver the required bandwidth and the majority of the effort will be directed at developing uncooled electroabsorption modulators and ILMs based on the novel 2D grating laser which provides single wavelength operation without requiring the regrowth needed by DFBs or DBRs. 40Gb/s transceiver electronics will be developed and the transmitter and receiver circuits will be integrated into a complete transceiver prototype. Vital support activities, such as systems modelling of both SMF and MMF links and EMC/EMI design of the transceiver, will also be undertaken. The major outcome of the project, namely the development of the prototype transceiver, should place the UK with a product early in the lifecycle of the 40Gb/s datacommunications market.
