It has recently been reported that optical pulses propagating through a tapered fiber immersed in heavy-water( D2O) yield an broad and flat SC spectrum because the dispersion characteristics of the fiber is flattened at zero dispersion around 1064 nm. In the present paper, we analyzed numerically properties of the SC generation for the tapered fiber in D2O in more detail. The influence of incident light pulse parameters and waist length of a tapered fiber on SC spectra was also examined. From these analyses, it was found that wide SC spectrum with a spectral width of 412 nm measured at 20 dB less than the central maximum intensity was generated from optical pulses with a pulse width of 125 fs and a peak power of 25 kW at central wavelength of 1064 nm due to propagation even in a tapered fiber with a waist length of 10 mm.}, pages = {439--447}, title = {重水中テーパーファイバーからのスーパーコンティニュウム光パルスのスペクトルと位相の数値解析―テーパーウエスト長による影響―}, volume = {40}, year = {2011} }
