A low cost sidelobe suppressed tunable microwave photonic bandpass filter is proposed and experimentally demonstrated. The filter is based on a multi‐wavelength ring laser and a segment of single mode fiber as a dispersive element. Through adjustment of the power profile of the multi‐wavelength laser to a bell shape, a filter frequency response without sidelobes is achieved. © 2009 Wiley Periodicals, Inc.
