摘要
提出了一种微流控电调谐非机械空间光开关器件,该器件的基本形式为"光输入阵列+光交换空间+光输出阵列"的结构,采用"水/油/水"液体棱镜作为偏光控制单元.在特定电压范围(30～110V)内,通过电润湿效应作用的液体棱镜光束偏转角可在约-15°～15°之间连续可调.由此可构造多种平面甚至立体光开关阵列.
A novel space optical switch device of optofluidic is proposed to solve the problems of electrical controlling without mechanical device.The basic structure of the switch includes a core exchange space sandwiched between two optical arrays.The basic unit of array is made from liquid prism as a beam control unit including three kinds of immiscible liquids（water / oil / water）.Through the electro-wetting effect,the beam deflection angle of the liquid prism can be adjusted about -15 °~15 °continuously in a specific voltage range（30 ~ 110 V）.Thus one can construct a variety of two-dimensional or even three-dimensional optical switch array.
