Abstract :
A near-traveling-wave semiconductor laser amplifier (SLA) has been used as a dual-function device to simultaneously perform optical amplification and receive baseband network control data in a multichannel subcarrier-multiplexed system. The dual-function SLA receives 100-Mb/s baseband signal from the electrical terminal with an error rate of less than 10/sup -9/ and improves the system power budget by 11 dB for five FSK channels (100-Mb/s each) in the 2 to 3-GHz band. Using SLAs as dual-function or multiple-function devices in broadband networks is an attractive means to enhance network functionality and performance.<>
