HIGH POWER TRANSMISSION OVER OPTICAL WAVEGUIDE WITH SUPPRESSION OF STIMULATED BRILLOUIN SCATTERING

摘要

A method of transmitting light along an optical fibre comprises launching into the fibre a high-power optical wave originating from one or more narrow-linewidth sources the optical wave having a phase angle which varies with time in such manner that Stimulated Brillouin Scattering is substantially suppressed. This permits the light to be transmitted along the optical fibre at optical powers above the power limit previously imposed by the onset of Stimulated Brillouin Scattering.
