| Abstract(in English) | It is well known that the spectra of optical short pulses with intense powers broaden extremely its width in transparent media, such as an optical fiber. Recently, the experimental results of supercontinuum spectrum generating in a conventional telecommunications fiber that was tapered have been reported. This may be due to enhanced spectral broadening in a tapered fiber designed to maximize nonlinear effects. In this paper, we evaluate numerically the dispersion and effective area distributions which are varying along the length of tapered fiber. For such a tapered fiber the supercontinuum generation was confirmed by numerical analysis based on a split-step Fourier method. Experimental verification of the spectrum using a femtosecond pulse from a Ti:sapphire laser is followed by the analysis and compared with the numerical calculations. |
