[0014] specific implementation
[0015] The scheme of the optical frequency generator proposed by the present invention has been verified through experiments, and the experimental device is as figure 1 As shown, the experimental process and results are described below in conjunction with the accompanying drawings.
[0016] Such as figure 1 As shown, in the experiment, the working wavelength of the tunable continuous wave laser is set to 1550.2nm, and the output power is 14dBm. The 2 ports of the circulator enter the non-zero dispersion-shifted fiber with a length of 2km in reverse, and the output power of the amplifier is 12dBm to stimulate the stimulated Brillouin scattering effect in the non-zero dispersion-shifted fiber. When the -1st order sideband of the phase modulator output is within the gain bandwidth of stimulated Brillouin scattering, this sideband will be amplified. The light output by the optical fiber is input to the 10:90 coupler through the circulator and ...
