High-Q single-bandpass photonic RF filter overcoming optical third-order dispersion based on programmable spectrum shaping of a broadband optical source

摘要

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 .
