一、前言集成光学研究集成光路的各种器件,并开把它们联接起来,构成微型化的集合体,以及研究其应用。就好像集成电路一样,不过它更复杂、加工更精致罢了。集成光路主要包括两大类元件: 第一类为无源器件——不改变激光束性质的器件,如光波导、薄膜透镜、薄膜棱镜、耦合器、反射器、滤波器等。 I. INTRODUCTION Integrated optics studies the various components of an integrated optical circuit and joins them together to form miniaturized aggregates and their applications. It’s like an integrated circuit, but it’s more complex and more elaborate. Integrated optical path consists of two main categories of components: the first is passive components - devices that do not change the nature of the laser beam, such as optical waveguides, thin-film lenses, film prisms, couplers, reflectors, filters and the like.
