چکیده
Abstract: Numerical examination of the solution of the boundary–value problem of the reflection and transmission of a plane wave due to a slab of an electro–optic structurally chiral material (SCM) indicates that the exhibition of the circular Bragg phenomenon by the SCM can be controlled not only by the sign and the magnitude of a dc electric field but also by its orientation in relation to axis of helicoidal nonhomogeneity of the SCM. Thereby, the possibility of electrical control of circular–polarization filters has been extended.

O ct 2 00 6 Theory of electrically controlled exhibition of circular Bragg phenomenon by an obliquely excited structurally chiral material
The boundary–value problem of the reflection and transmission of a plane wave due to a slab of an electro–optic structurally chiral material (SCM) is formulated in terms of a 4×4 matrix ordinary differential equation. The SCM slab can be locally endowed with one of 20 classes of point group symmetry, and is subjected to a dc voltage across its thickness. The enhancement (and, in some cases, the...
متن کاملOptical crossover phenomenon due to a central 908-twist defect in a chiral sculptured thin film or chiral liquid crystal
We present a theoretical analysis of a remarkable phenomenon evinced by a periodic structurally chiral material—for example, a chiral sculptured thin film (STF) or a chiral liquid crystal—with a central 908-twist defect illuminated with normally incident, circularly polarized light. Based on the coupled-wave theory (CWT), an approximate but closed-form solution of the relevant boundary-value pr...
متن کاملElectrically Controlled Bragg Resonances of an Ambichiral Electro–optic Structure: Oblique Incidence
The Pockels effect can increase the effective birefringence of ambichiral, electro–optic rejection filters made of materials with a 4̄2m point group symmetry, when a dc electric field is applied parallel to the axis of nonhomogeneity. The reflectances and the transmittances of such an ambichiral structure for obliquely incident plane waves is solvable through a boundary–value problem that is for...
متن کاملNarrowband and ultranarrowband filters with electro–optic structurally chiral materials
When a circularly polarized plane wave is normally incident on a slab of a structurally chiral material with local 4̄2m point group symmetry and a central twist defect, the slab can function as either a narrowband reflection hole filter for co–handed plane waves or an ultranarrowband transmission hole filter for cross–handed plane waves, depending on its thickness and the magnitude of the applie...
متن کاملElectrically controlled transfer of spin angular momentum of light in an optically active medium.
Spin is an intrinsic property of the photon. A method for using an externally applied dc electric field to manipulate the transfer of spin angular momentum of light in an optically active medium is presented. To discuss this, we first develop a wave coupling theory of the mutual action of natural optical activity and the linear electro-optic effect. Besides being used for analyzing the electric...
