DESIGN AND PERFORMANCE EVALUATION OF NARROWBAND RECTANGULA OPTICAL FILTER BASED ON STIMULATED BRILLOUIN SCATTERING IN FIBER

摘要：

　　We propose a rectangular optical filter based on stimulated Brillouin scattering in fiber with tunable bandwidth from 50 MHz to 4 GHz at 15-MHz tuning resolution.The steep-edged rectangular shape of the filter is precisely controlled utilizing digital feedback revision of the pump light.The passband ripple is~1 dB by nonlinearity management of the pump and using the fiber with a single Brillouin peak.The extinction ratio of the filter is further enhanced using the polarization characteristics of the Brillouin scattering.Based on this filter,we demonstrate a sub-band extraction of a multi-band orthogonal frequency division multiplexing signal,which shows the potential ability of the filter in the fields of optical and microwave signal processing.
