Abstract
In addition to the well-known problem related to the growing demands in telecom fiber optical data transmission lines with extended bandwidth in recent years the researchers developed an interest in mode-locked fiber lasers of 1600-1700 nm spectral region in a number of biomedical applications. The known approach to get the generation in this range uses the Er-doped fiber mode-locked seed source of telecom range. The output ultrashort pulse then propagates in nonlinear optical fiber with anomalous dispersion undergoing the Raman shift to the longer wavelengths. We propose a method to control the characteristics of the output Raman soliton spectrum adjusting the polarization of the pump pulse at the input of the nonlinear fiber. We have shown that this method allows to tune the wavelength of the output spectrum maximum in the whole range (1600-1700 nm) while the output power remains constant. Our simulation results agree with experimental observations.
