6. Polarization attraction coupled with optical amplification
An interesting development of the device shown in figure 12 is to combine, within the same optical fiber, the polarization stabilization effect described above with a Raman amplification process.
Raman amplification in optical fibers is based on the transfer of energy from a pump wave to a signal wave of longer wavelength, via the excitation of vibrational modes in the silica. The frequency range giving maximum gain is around 13.2 THz in conventional optical fibers (i.e. around...
