Abstract:	摘要： We demonstrate an oscillation-free implementation of an optical beam control device with reconfigurable fluidic lens. In the activation state, the incident light passing through the interfacing medium (water or air) is diverged by the deformed plano-concave fluidic lens, resulting in a dark state. In the non-activation state, the elastic membrane recovers to its original state of the flat interface-this has the effect of transmitting the incident light and opening the switch. We also demonstrated a white-light switch with tunable response times ranging from 50 ms to 200 ms. The actuation mechanism has tremendous potential in light shutters, variable optical attenuators, and displays. 出版者： AIP Publishing 出版日期： 2012-08-13 出處： Applied Physics Letters, 2012-08, Vol.101 (7), p.71901 資源來源： AIP Journals (American Institute of Physics) 識別號： ISSN: 0003-6951 識別號： EISSN: 1077-3118 識別號： DOI: 10.1063/1.4745771
