We demonstrate microwave modulation of an optical beam by using the electro-optic effect in total internal reflection near the critical angle. An internally reflected mode-locked laser beam and a microwave field electrooptically interact near the surface of a KDP crystal to produce new modulation frequencies in the reflected beam. Its microwave sensitivity is approximately 3 mV/V radicalHz. This technique, described by the boundaryvalue problem of nonlinear optics, provides a sensitive method to study the physical nature of the electro-optic effect in total internal reflection. Fundamental optical and electrical properties of the electro-optic effect in total internal reflection are presented.
我们通过利用临界角附近全内反射中的电光效应来演示光束的微波调制。一个内反射锁模激光束和一个微波场在磷酸二氢钾(KDP)晶体表面附近发生电光相互作用,从而在反射光束中产生新的调制频率。其微波灵敏度约为3 mV/V√Hz。这种由非线性光学的边值问题描述的技术,提供了一种研究全内反射中电光效应物理本质的灵敏方法。文中介绍了全内反射中电光效应的基本光学和电学特性。
