As radio-frequency (RF) filtering plays a vital role in electromagnetic devices and systems, recently photonic techniques have intensively been studied to implement RF filters to harness wide frequency coverage, large instantaneous bandwidth, low frequency-dependent loss, flexible tunability, and strong immunity to electromagnetic interference. However, one crucial challenge facing the photonic RF filter (PRF) is the less impressive out-of-band rejection. Here, to the best of our knowledge, we…
