贝尔实验室的一个工作组论证了一只快速、小功率的光开关,它是一种建立在二种液体界面上表面张力的电调制原理上的器件,Appl.Phys.Lett一月号上对它作了介绍,并且在今年四月的OFC会议上将要对它进行讨论。它的结构和动作都很简单。它具有一个可动另件,该另件是由一根含有电介质的毛细管内灌入水银的小嵌片。它是按下述方式进行工作的:因为水银嵌片与毛细管壁之间的间隙非常小(10A
A team at Bell Labs demonstrated a fast, low-power optical switch that is a device based on the principle of electrical modulation of the surface tension at two liquid interfaces. Appl. Phys. Lett January It was introduced and will be discussed at the OFC meeting in April this year. Its structure and movement are simple. It has a movable member which is a small insert of mercury charged in a capillary containing a dielectric. It works as follows: Because the gap between the mercury insert and the capillary wall is very small (10A
