贝尔实騐室的科学家们研制了一种为激光使用的新型光开关。在未来微小光路中,开关能用来使激光束载上电话呼叫和其他数据。磁控开关通过石榴石单晶薄膜可以调制光,有朝一日它可能成为光通讯系统微型光路的心脏。目前实騐形式的实际开关约宽3/4时。但是,可以进一步缩小它来满足光通讯系统的特殊要求。 Bell Labs scientists have developed a new optical switch for use with lasers. In the future tiny light path, the switch can be used to make the laser beam phone calls and other data. The magnetron switch modulates light through a garnet single crystal film, one day it may become the heart of a microchannel in an optical communication system. The actual experimental form of the actual switch about 3/4 hours wide. However, it can be further narrowed to meet the special requirements of optical communication systems.
