Abstract
A long fiber ring as the simple filter for carrier- suppression of microwave photonics signals is proposed. It is based on stimulated Brillouin scattering. The filter can be used to reduce RF loss in radio on fiber system. The modulation depth and RF signal gain increase with the power of input modulated signal. A modulation depth of 100% can be easily attained at a lower input power. The experimental results are well in agreement with the theoretical predictions. Approximately 26 dB of RF signal gain in the band from 1 GHz to 18GHz is achieved in the experiment with this technique. Finally, the transmission experiment shows that the performance of radio on fiber system is effectively improved with the filter.
