The analytical expression for the self-Kerr nonlinear coefficient in a three-level V-type atomic medium is found in the presence of the Doppler effect. Based on the analytical results, we have analyzed the enhancement and control of the Kerr nonlinear coefficient under the condition of electromagnetically induced transparency. It is shown that the Kerr nonlinear coefficient is significantly enhanced around the resonant frequency of both the probe and coupling fields.

In this paper, we report a numerical calculation of the influence of structural parameters on the supercontinuum generation of photonic crystal fibers. A photonic crystal fiber based on the fused silica glass, eight rings of air holes ordered in a hexagonal lattice, is proposed. Guiding properties in terms of dispersion and confinement loss of the fundamental mode are also studied numerically. As a result, the broadband width of the supercontinuum spectrum will increase when the lattice pitch decreases or the diameter of air hole in the cladding increases.

This paper deals with the elastica and buckling loads of the nonlinear elastic tapered cantilever columns subjected to an axial load at the free end. The column cross section is rectangular, where the width and depth vary linearly with the column axis.
