Paper Abstract

We described a nonlinear optical metamaterial formed by randomly dispersing coated core-shell nano-spheres in aligned nematic liquid crystals. Such material will exhibit effective refractive indices ranging from negative, through zero to positive values. The nano-spheres dispersed liquid crystal possesses an effective birefringence that is larger than the natural birefringence of the host liquid crystal, which effectively enhances the nonlinear optical response associated with optical field induced director axis reorientation.
