Abstract:
1. An optical transmitter having SBS suppression, the optical transmitter comprising: a) a signal generator that generates a SBS suppression signal at an output; b) a laser having an electrical input that is electrically coupled to the output of the signal generator, the laser generating an optical signal at an output having a line width that is broadened by the SBS suppression signal and having AM noise; c) a signal processor having an electrical input that is electrically coupled to the output of the signal generator, the signal processor generating a modified SBS suppression signal at an output; and d) a modulator that is optically coupled to the output of the laser and that is electrically coupled to the output of the signal processor, the modulator modulating the optical signal with a payload modulation signal and with the modified SBS suppression signal, thereby generating a payload modulated optical signal having SBS suppression, wherein the modified SBS suppression signal reduces the AM noise in the payload modulated optical signal.
