Claim 8:
9. The tunable narrow-linewidth photo-generated microwave source based on polarization control according to claim 1, wherein a central reflection wavelength of the high-reflectivity fiber grating is a laser output wavelength of 1550.12 nm, a 3 dB reflection spectrum width of 1.2 nm, and a central wavelength reflectivity greater than 99.95%; a central wavelength of a slow-axis reflection peak of the low-reflectivity polarization-maintaining fiber grating is 1550.12 nm, and a fast-axis reflection peak of the low-reflectivity polarization-maintaining fiber grating is 1550.50 nm, with a reflectivity of both 60%.
