High-Q Single-Bandpass Photonic RF Filter Overcoming Optical Third-Order Dispersion Based on Programmable Spectrum Shaping of a Broadband Optical Source

We demonstrate a novel reconfigurable photonic RF filter which can achieve theoretically infinite Q factors. Single sinc-shape passband with Q = 634 and flat-top passband with Q = 76 are demonstrated experimentally when the passband center is tuned at 18 GHz.
