In this article, a simple approach for photonic generation of microwave signal using a dual‐wavelength single longitudinal mode fiber ring laser is proposed and demonstrated.A narrow transmission band fiber Bragg grating (FBG) based Fabry‐Perot cavity is used to select the longitudinal mode. A FBG with reflectivity of 99.5% is used together with 2‐m unpumped erbium‐doped fiber acting as saturable absorber. Stable dual‐wavelength single longitudinal mode fiber lasers with a wavelength separation of approximately 0.057 nm are experimentally realized. By beating the dual‐wavelength fiber lasers at a photodetector, photonic generation of microwave signal at 7.129 GHz is successfully obtained. Both of the laser emission and generated microwave signal have good stability at room temperature. © 2012 Wiley Periodicals, Inc.
