The effective mode area and nonlinearity of a proposed fiber with cladding made of uniaxial anisotropic crystal material are derived by fully vectorial method, the influence of kcl, the ratio of the extraordinary to the ordinary ray index, on optical field distribution and nonlinear coefficient γ is investigated theoretically. The results indicate that kcl has no impact on optical field distribution...
In recent years, metamaterials are obtained a lot of attentions, because of the materials with some special properties, such as negative index, tunable electric permittivity, artificial magnetism, and strong chirality. Particularly, transformation optics was introduced this filed, various functional devices were designed. Although a variety of functional devices on the theory and practice have been...
A fiber with cladding made of uniaxial anisotropic crystal material whose optical axis is parallel to the axis of fiber was proposed, and the nonlinear parameter γ of this kind of fiber was investigated theoretically. The ratio (kcl) of the extraordinary to the ordinary ray index was introduced and the influence of parameter kcl upon γ was examined by exact vector modes method. The calculated results...
