A novel multitap coherence‐free photonic bandpass RF filter utilizing the cross‐gain modulation property of the semiconductor optical amplifier to convert a coherent RF‐modulated laser carrier to a low‐coherence light that is sliced and delayed to realize a stable transversal RF filter. An 8‐tap photonic RF bandpass filter operating at 2.25 GHz with more than 15 dB rejection is experimentally demonstrated. © 2007 Wiley Periodicals, Inc.
