Affordable gigabit networks are necessary for communication at high data rates in the business and scientific world. To make affordable gigabit networks a reality, low cost multi-gigabit links are essential. This project will develop front ends for low cost multi-gigabit networks by developing 10Gb/s transmitter and receiver modules for multi-gigabit fiber optical networks. Different designs will be used to address the short and long reach application requirements. The Phase I project developed, designed and tested a prototype transmitter and receiver pair operating at 10Gb/s. The transmitter and receiver meet all operating design requirements and specifications. The Phase II project will further improve the performance and reduce the production cost of the transmitter and receiver modules using vertical cavity surface emitting laser based technologies. The short reach transmitter will be based on low cost direct modulation of laser, whereas an integrated laser and modulator will be used in the long reach transmitter module.

Commercial Applications and Other Benefits as described by the awardee: There is tremendous demand for data bandwidth for every conceivable scientific and commercial applications. The gigabit fiber optical links for high speed data transmission for local data networks as well as for the gateways for external communications should have a huge market potential.
