Stimulated Brillouin scattering for optical single sideband modulation in RoF system

Abstract

Stimulated Brillouin scattering in fiber is used to realize optical single sideband modulation of the 11GHz radio over fiber (RoF) system. It amplifies the lower sideband of modulated signals and attenuates the upper sideband. Optical single sideband modulation is then achieved which reduces the dispersion caused by traditional double sideband modulation in RoF system. The performance of 11GHz RoF system is then improved. In the experiment, about 2dB SNR gain is attained at 10Mbit/s signal with QPSK modulated format.
