摘要

提出了一种用于可变光纤耦合的液体微透镜的二维横向定位和聚焦系统。横向定位和焦点调整是通过电润湿介质完成的。该芯片是在透明的耐热玻璃衬底上制造的,并配备了二维电极阵列,具有明确的微观结构,可以精确定位液体微透镜。该系统被用作可变光纤耦合元件,并测量了与光纤耦合的光功率随外加电压的变化。应用,如自适应波前传感,光学镊子,或三维聚焦控制显微镜设想。

Reconfigurable liquid micro-lens system for variable fiber coupling
A system capable of both two-dimensional lateral positioning and focusing of a liquid micro-lens for variable fiber coupling is presented. Lateral positioning and focus adjustment is accomplished by electrowetting-on-dielectrics. The chip is fabricated on a transparent Pyrex substrate and is equipped with a two dimensional array of electrodes featuring a well-defined microstructure which allows accurate positioning of the liquid micro-lens. The system is used as a variable optical fiber coupling element, and measurements of optical power coupled to a fiber as a function of the applied voltage are presented. Applications such as adaptive wave front sensing, optical tweezers, or three- dimensional focus control for microscopy are envisaged.
