光电子器件不仅在性能方面，而且在集成水平上都发生飞速的演变。以光波导和光纤的使用来说，光电子系统正开始象电子电路一样飞速地发展。电子元件的光学模块包括二极管激光器、探测器、调节器、开关和衰减器，所有这些提供了一个电－光界面。这种演变的根本目的是使用一器件 Optoelectronic devices not only in terms of performance, but also at the level of integration have evolved rapidly. With the use of optical waveguides and optical fibers, optoelectronic systems are beginning to grow as rapidly as electronic circuits. Optical components for electronic components include diode lasers, detectors, regulators, switches and attenuators, all of which provide an electro-optic interface. The fundamental purpose of this evolution is to use a device
