Abstract :
We demonstrate a rectangular microwave photonic filter based stimulated Brillouin scattering effect in optical fiber. The rectangular spectral response is achieved by using both multi-tone and frequency-sweeping Brillouin pump schemes, combined with digital feedback compensation. The filter selectivity is improved by using pump-splitting dual-stage scheme. A rectangular microwave photonic filter with as high as 45-dB selectivity at 1-GHz bandwidth has been achieved.
