Experimental and phenomenological aspects of circular birefringence and related properties in transparent crystals

Abstract

Here, we review the history, theory, measurement technique and experimental results on gyrotropic phenomena including optical rotation (optical activity), electrogyration, the Faraday effect and magneto-electrogyration in transparent crystals, including examples of structural phase transitions. Relations to the absolute structure are discussed and model calculations are performed on the basis of electronic polarizability and crystal structure.

Determination of the components of the gyration tensor of quartz by oblique incidence transmission two-modulator generalized ellipsometry

“…We will use the propagation description first given by [24], which uses the constitutive equations given by Born [25]. This model is widely used in the literature [23,[26][27][28], particularly in experimental work, and gives the possible values of the refractive index n, for a given direction of the wave normal. Although this approach is only approximate, it has been shown to be accurate as long as the birefringence of the investigated crystal is not huge [29], as this model describes the phenomenon of optical activity within an accuracy of the product of the linear birefringence in the direction of observation by the gyrotropy parameters [28].…”

Non-linear optical properties and absolute structure of metastable 4-methyl benzophenone

“…The number of completely determined tensors for optical rotation is still very limited and only a few have been correlated with the absolute structures [20]. The set of parameters best describing the experimental findings is set # 10 in accordance with the experimental findings, although the calculated value is considerably smaller.…”

“…The procedure is described in detail elsewhere, see for a summary Kaminsky, 2000 [20] varying angles is analysed with a second polarizer behind the sample (tilter method). The intensity then depends on the geometrical parameters [incidence angle (tilt angle ), angles of incident polarization and that of the analyzer, and resultant azimuth and ellipticity of the elliptically polarized wave as well as sample extinction direction.…”

Электросенсор На Основе Эффекта Электрогирации В Кристалле Вольфрамата Свинца

“…DOI: 10.21883/PJTF.2017.08. 44530.16496 Явление оптической электрохиральности было открыто более 50 лет назад и до настоящего времени привлекает исследователей [1,2]. Первое предложение использовать эффект электрохиральности для измерения высоковольтных электрических напряжений было сделано в работе [3] на примере кристаллического кварца.…”
