Abstract

We propose and demonstrate a simple approach to optical generation of microwave signal by exploiting a uniform fiber Bragg gating (FBG) based double-ring laser and a saturable absorber. Parallel arranged uniform FBGs have a wavelength spacing corresponding to the microwave signal. A piece of unpumped polarization-maintaining erbiumdoped fiber (PM-EDF) serves as a saturable absorber, ensuring the dual-wavelength single longitudinal mode operation. Stable dual-wavelength single longitudinal mode lasers are obtained in the experiment. A microwave signal at 28.38 GHz is successfully generated by beating the dual-wavelength single longitudinal mode lasers.
