Abstract—A novel approach for the generation of high-fre-
quency microwave signals using a dual-wavelength single-longitu-
dinal-mode fiber ring laser is proposed and demonstrated.In the
proposed configuration,a dual-wavelength fiber Bragg grating
(FBG) with two ultranarrow transmission bands in combination
with a regular FBG is used to ensure single-longitudinal-mode
operation of the fiber ring laser.A semiconductor optical amplifier
s employed as the gain medium in the ring cavity.Since the two
asing wavelengths share the same gain cavity,the relative phase
fluctuations between the two wavelengths are low and can be used
to generate a low-phase-noise microwave signal without need of a
microwave reference source.Three dual-wavelength ultranarrow
transmission-band FBGs with wavelength spacing of 0.148,0.33,
and 0.053 nm are respectively incorporated into the laser.Mi-
crowave signals at 18.68,40.95,and 6.95 GHz are obtained by
beating the dual wavelengths at a photodetector.The spectral
width of the generated microwave signals as small as 80 kHz with
a frequency stability better than 1 MHz in the free-running mode
at room temperature is obtained.
