光隔离器在光信息技术实验中的应用

Application of Optic Isolator in Optical Information and Technology Experiment

介绍了光隔离器的结构及工作原理,并通过在二项光信息实验中应用光隔离器的实例,说明将它放置在半导体光源输出光之后能够使实验系统稳定,可以获得可靠的测量数据。1550nm波长的光隔离器,价格便宜,适宜在教学实验中应用。

In optical fiber technology, optical isolators are indispensable devices for eliminating the reflections between the fiber and light source and between fibers. The structure and theory of optical isolator are presented in this paper. And the results from optical information and technology experiments show that the stable system can be obtained when the optical isolator is connected with diode laser. The optical isolator is suit for experimental teaching due to its lower price.
