Abstract
The incorporation of the Pockels effect in structurally chiral materials (SCMs) engenders new modalities for control manipulation of the circular Bragg phenomenon (CBP). The boundary-value problem of the reflection and transmission of a plane wave due to a slab of an electro-optic SCM is formulated in terms of a 4×4 matrix ordinary dfferential 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 production) of the CBP by the application of a dc electric field across the thickness of the SCM slab has switching and circular-polarization-rejection applications in optics.
