Optical activity and Faraday effect in bismuth germanium oxide Bi12GeO20
摘要
在430.0～800.0 nm波长范围研究了Bi_(12)GeO_(20)的旋光性和法拉第效应.分析表明,锗酸铋的旋光频散特性可以用Drude的分子旋光模型来描述.它的较强的法拉第效应使它有可能用于光学非互易器件或偏振旋转器中.
Abstract
Optical activity and Faraday effect in bismuth germanium oxide (Bi12GeO20) were investigated in the spectral region 430.0-800.0 nm. It was found that the best fitted model of optical activity in Bi12GeO20 to the experimental results was the Drude model of molecule coupled oscillators. However the relation of optical activity with the crystal structure is not clear yet. Due to the quite strong Faraday effect, Bi12GeO20 could possibly be applied to some optical nonreciprocal or polarization devices.
