The problem of the coupling of a surface dielectric grating to a structurally chiral volume grating is formulated and solved. The volume grating is a chiral sculptured thin film, which exhibits the circular Bragg phenomenon in distinct wavelength regimes. Two distinct interactions are involved: (i) those of linearly polarized and circularly polarized modes, and (ii) those of nonspecular modes with the specular Bragg phenomenons. Numerical studies show that the circular Bragg phenomenon is virtually immune to the presence of the surface grating. Hence, chiral STF filters can be diffraction-coupled to other optical elements.

The Bruggeman approach is implemented to homogenize a collection of identical, similarly oriented, electrically small, ellipsoidal particles with intensity-dependent refractive index that are dispersed randomly and homogeneously in an isotropic, linear, dielectric host material. The homogenized composite medium is assumed to be cubically nonlinear and anisotropic, in the simplest approximation. The anisotropy of nonlinearity may be considerably different from the anisotropy of the linearity. The possible enhancement of nonlinearity is also anisotropic, with the most desirable performance along the shortest principal axis of the ellipsoidal particles. [ABSTRACT FROM AUTHOR]

A material combining both mirror-conjugated and racemic chirality properties is characterized and classified within the context of linear bianisotropic mediums. Planewave propagation in the chosen material is studied with particular emphasis on the interaction of different and no handedness along certain specified directions. Comparison is made with isotropic chiral mediums as well as uniaxial bianisotropic mediums. [ABSTRACT FROM AUTHOR]
