Abstract

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. Microwave Opt Technol Lett 49: 1103–1106, 2007; Published online in Wiley InterScience (www.interscience.wiley.com). DOI 10.1002/mop.22352
