Abstract

It was reported recently that optical pulses propagating through a tapered fiber (TF) immersed in heavy water (D₂O) or photonic crystal fiber (PCF) of special design yield a broad and flat supercontinuum (SC) spectrum because the fiber dispersion characteristics are of low dispersion: around 1000 nm. This work was undertaken to investigate spectral intensities and phase distributions of SC pulses generated in low-dispersion fibers. Results show that PCF with group velocity dispersion (GVD) distributions having an extremum value of zero dispersion can be used at short fiber length for applications where the phase distribution is a concern.
