有耗光子结构中的磁法拉第旋转

Magnetic Faraday rotation in lossy photonic structures

A. Figotin, I. Vitebskiy

摘要:

磁法拉第旋转在光学和微波领域有着广泛的应用。在均匀磁光材料中,这种效应非常弱。一种增强它的方法是将磁性材料并入高Q光学谐振器中。磁光谐振器的一个问题是,随着法拉第旋转,吸收和线性双折射也会急剧增加,从而损害器件性能。另一个问题是输出光的强椭圆率。我们讨论了如何在光学微腔和慢波谐振腔的情况下解决上述问题。我们表明,慢波谐振器有一个根本的优势,当涉及到法拉第旋转损耗磁性材料的增强。

英文摘要:

Magnetic Faraday rotation is widely used in optics and MW. In uniform magneto-optical materials, this effect is very weak. One way to enhance it is to incorporate the magnetic material into a high-Q optical resonator. One problem with magneto-optical resonators is that along with Faraday rotation, the absorption and linear birefringence can also increase dramatically, compromising the device performance. Another problem is strong ellipticity of the output light. We discuss how the above problems can be addressed in the cases of optical microcavities and a slow wave resonators. We show that a slow wave resonator has a fundamental advantage when it comes to Faraday rotation enhancement in lossy magnetic materials.
