An optical wavelength tracking receiver can be constructed to automatically follow and amplify a drifting optical signal while using the Stimulated Brillouin Amplification (SBA) principle. With SBA, a received optical signal at a particular wavelength will be amplified if a pump signal is injected in the opposite direction at a lower frequency.
