Abstract
The authors demonstrate the use of self-pulsating laser diodes as fast-tunable (<or=1 ns), frequency-shift keyed (FSK) microwave subcarrier transmitters in local-area subcarrier frequency-division multiple access (SFDMA) lightwave networks. They show that by using commercially available compact-disk self-pulsating lasers, a network supporting four users each transmitting at 150 Mb/s FSK is feasible, and can be extended to 12 FSK subcarrier channels at 200 Mb/s if the self-pulsating frequency is extended to 12 GHz.
