ABSTRACT: Noise generators and standalone noise sources can address the critical needs of Stimulated Brillouin Scattering (SBS) reduction by driving coherence spreading to minimize retroflected scattering, allowing for high optical power transmission. Coherence spreading using a random noise source reduces each laser module’s sharp waveform (peak power) by modulating the phase of the laser. Although the peak power is reduced, the average power remains the same, therefore the overall optical power of the laser is maintained while at the same time reducing the negative effects of SBS.
