| Popis: | We have demonstrated a simple supercontinnum source based on an erbium-doped fiber-ring laser incorporating both schemes of nonlinear polarization rotation and stimulated Raman scattering (SRS). The proposed source obtains the spectral width of 165 nm covering from 1523 to 1688 nm accompanied with a flattened spectrum-ripple less than 3 dB. The small threshold pumping power around 50 mW could effectively activate the SRS so as to significantly expand the spectra for longer wavelength approaching. The relative intensity noise of the laser could be as low as -134 dBc[1 Hz] at the band larger than 5 GHz without harmonics caused by the fiber ring. |
