S. Tonda-goldstein et al., Stimulated Brillouin scattering for microwave signal modulation depth increase in optical links, ELECTR LETT, 36(11), 2000, pp. 944-946
Carrier reduction from a weakly modulated optical signal is required in hig
hly linear optoelectronic links. The proposed solution uses stimulated Bril
louin 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.
