Abstract

The effect of the polarization state on electro-optic coupling is studied by using the wave coupling theory of the linear electro-optic effect. The numerical results show that the polarization state obviously influences the electro-optic coupling. The conditions for realizing perfect coupling are emphasized. As an application of perfect coupling, a novel polarization rotator, which can rotate the polarization of a light beam with an arbitrary angle but keep the output intensity unchanged, is presented.

摘要

利用线性电光效应的波耦合理论研究了偏振态对电光耦合的影响。数值结果表明，偏振态对电光耦合有显著影响。强调了实现完美耦合的条件。作为完美耦合的一个应用，提出了一种新型偏振旋转器，它可以将光束的偏振旋转任意角度，同时保持输出强度不变。
