Abstract

In this paper, we report a numerical study of the supercontinuum (SC) generation in solid-core photonic crystal fibers infiltrated with water-ethanol mixtures. A photonic crystal fiber is constructed as borosilicate glass NC21, which consists of 7 rings of air holes infiltrated with water-ethanol mixtures. We also considered numerically the influence of concentration of the ethanol solution on the dispersion of the fundamental mode. SC generation was demonstrated for the fiber long 20 cm with a pump pulse of 200 fs, the coupled energy of 0.5 nJ at the center wavelength of 1064 nm in the normal dispersion regime. The concentration of ethanol infiltrated to the fiber, the pulse of duration and the pump energy are investigated.
