液态物质填充的空芯光子晶体光纤中超连续谱产生的研究

In this paper, we report the numerical simulation of the hollow-core photonic crystal fiber filled with liquid materials in the air core. The dispersion features of chloroform-filled photonic-crystal fibers(PCF) were researched when the fiber performed with the total reflection principle. Finally the nonlinear propagation in the chloroform-filled photonic-crystal fibers of femtosecond laser pulses with center wavelength in 800nm was investigated theoretically. Because of the filled materials’s preferable nonlinear coefficient and dispersion properties, wider supercontinuum spectrum were obtained in the liquid-filled hollow-core bandgap fiber in the case of low attenuation.
