| Summary: | The present invention relates generally to the field of telecommunications and, in particular, to the suppression of stimulated Brillouin scattering in optical transmissions.
A transmitter that performs stimulated Brillouin scattering suppression is provided. The transmitter includes a non-linear device having an optical input adapted to receive an optical signal, an amplitude modulation input adapted to receive an amplitude modulation signal, a phase modulation input and an output. The transmitter also includes a stimulated Brillouin scattering (SBS) oscillator/driver having first and second oscillators coupled to the phase modulation input of the non-linear device and an amplifier coupled to the output of the non-linear device. The transmitter further includes a laser coupled to the optical input of the non-linear device. |
