| Abstract(in English) | Highly efficient generation of spectrally-broad single-mode supercontinuum(SC) light in conventional tapered fibers is well documented. It has been recently reported that optical pulses propagating through a tapered fiber immersed in heavy water(D_2O) yield an broad and flat SC spectrum because the dispersion characteristics of the fiber is flattened at zero dispersion around 1064nm. In this report, we present in detail the numerical analysis of the SC generation for the tapered fiber in D_2O. The influence of incident light pulse parameters and waist length of tapered fiber on SC spectra was also examined. From these results, it was found that a 468nm wide SC spectrum at 20dB less than the central maximum intensity is generated from optical pulses with a pulse width of 250fs and an average power of 90mW at central wavelength of 1064nm due to propagation even in a tapered fiber with a waist length of 10mm. |
