A tunable and dispersion-insensitive two-tap microwave photonic filter(MPF) with a complex coefficient is proposed and demonstrated.By simply adjusting a polarization controller(PC) in one tap,the filter can be tuned over the entire free spectral range(FSR) while keeping the shape of the filter unchanged.Because the two taps are both single-sideband(SSB) modulated,the filter has high tolerance to fiber dispersion.The transmission response of a system with 25-or 40-km single-mode fiber(SMF) was measured and compared with an MPF with one double sideband(DSB) modulation tap.The proposed MPF shows much better performance for long-distance fiber transmission.
A tunable and dispersion-insensitive two-tap microwave photonic filter (MPF) with a complex coefficient is proposed and demonstrated. Simply modulated a polarization controller (PC) in one tap, the filter can be tuned over the entire free spectral range (FSR ) while keeping the shape of the filter unchanged. Both of the two taps are both single-sideband (SSB) modulated, the filter has high tolerance to fiber dispersion. The transmission response of a system with 25-or 40-km single-mode fiber (SMF) was measured and compared with an MPF with one double sideband (DSB) modulation tap. Proposed MPF shows much better performance for long-distance fiber transmission.
