Photonic generation of microwave signals using dual-wavelength single-longitudinal-mode fiber lasers
摘要：
Photonic generation of microwave signals is demonstrated with a dual-wavelength single-longitudinal-mode erbium-doped fiber ring laser. Microwave signal with a frequency of 21.07 GHz is obtained by aligning the reflection band of a uniform fiber Bragg grating to the two transmission peaks within a fiber Bragg grating-based Fabry–Perot filter. Stable dual-wavelength single-longitudinal-mode operation is guaranteed by means of the combined filtering effect of a saturable absorber and the Fabry–Perot filter. This approach provides an effective solution to the photonic generation of high-frequency microwave signals.
