Resonant photoelastic effect in Bi12SiO20
Abstract
It is established experimentally that deformations occurring in a gyrotropic Bi12SiO20 crystal during the resonant excitation of a standing elastic wave lead to the modulation of the azimuth and ellipticity of polarized light. The polarization relationships obtained here are explained in terms of a model which allows for induced birefringence and natural optical activity. An observation of the effect of elastic gyration during deformation along the 111-line axis is also reported.
