Reconfigurable Microwave Photonic Bandpass Filter Based on Silicon Nitride Microring and Carrier Separation
This study proposes a reconfigurable microwave photonic bandpass filter based on an Add-Drop silicon nitride microring filter via optical single sideband modulation and optical carrier separation. The measured bandwidth and out-of-band rejection ratio of the proposed microwave photonic filter are 726 MHz and 37.0 dB, respectively. Further, a filter with a frequency tuning range of 1.64--23.41 GHz can be achieved by tuning the optical carrier's wavelength. In addition, the bandwidth can be adjusted to 0.683--2.246 GHz with an out-of-band rejection ratio of more than 26 dB by changing the coupling coefficients of the microring resonator.
