Abstract
We demonstrate the implementation of a widely tunable microwave signal generator based on a dual-polarization fiber grating laser. The frequency is continuously tuned from 1.8 to 15.1 GHz, by transversely loading the laser cavity to change the intracavity birefringence with the assistance of a PZT based mechanical device. The response time rate of tuning is about 90 MHz/μs and the intensity fluctuation at different frequencies is less than ±1.5 dB.
