摘要：

We demonstrate a silicon-based microwave photonic filter(MPF) with flattop passband and adjustable bandwidth. The proposed MPF is realized by using a 10 th-order microring resonator(MRR) and a photodetector,both of which are integrated on a photonic chip. The full width at half-maximum(FWHM) bandwidth of the optical filter achieved at the drop port of the 10 th-order MRR is 21.6 GHz. The ripple of the passband is less than 0.3 dB, while the rejection ratio is 32 dB. By adjusting the deviation of the optical carrier wavelength from the center wavelength of the optical bandpass filter, the bandwidth of the MPF can be greatly changed. In the experiment, the FWHM bandwidth of the proposed MPF is tuned from 5.3 to 19.5 GHz, and the rejection ratio is higher than 30 dB.
