集成光学的研究焦点在过去两三年里一直在变化,这一点本刊及其它杂志都曾指出过。在寻找新的工作物质上的努力逐渐减退,当前,注意中心转到使现有器件具有更多更好的性能和设计新的器件结构方面。 这些不仅是一种新兴技术将要出现的预兆,而且还开始报导一些针对应用的研究工作。总之,用个比喻的说法,集成光学看来要进幼儿园了。 The focus of integrated optics research has changed over the past two or three years, as has been pointed out in this and other magazines. Efforts to find a new working substance have diminished. At present, attention is paid to getting the existing devices to have more and better performance and designing new device structures. These are not only a harbinger of emerging technologies, but are also beginning to cover some research on applications. In short, using a metaphor to say, integrated optics seems to be entering kindergarten.
