Abstract :
Carrier reduction from a weakly modulated optical signal is required in highly linear optoelectronic links. The proposed solution uses stimulated Brillouin scattering (SBS) that occurs in optical fibres to deplete the carrier and leave the modulation sidebands unchanged. A modulation depth gain of >20 has been obtained using this method.
