Abstract :
The feasibility of using a frequency-modulated laser followed by an interferometer in a subcarrier multiplexed system is considered. It is found that a Fabry-Perot is not sufficiently linear for multichannel AM-SVB systems. A Mach-Zehnder has acceptable performance only if the losses in each arm of the interferometer are balanced, and a high-power laser diode is used.
