我们提出了一类紧凑的，基于流体的，干涉，可调光学元件：单光束微流体马赫-曾德尔干涉仪。相位延迟是通过光在流体-空气界面（弯月面）上的传播来实现的。弯月面曲率对器件透射率的影响被认为是使用三维光束传输方法，并示出是一个重要的器件参数。我们工程师的弯月面曲率使用单体表面化学，使其平坦，并发现实验响应与模拟相对应。该设备有一个共振在1.3妈妈与25分贝的消光比，后者可以通过改变弯月面的位置进行调整。(C)2005年美国物理学会。
We present a class of compact, fluid-based, interferometric, tunable optical components: the single-beam microfluidic Mach-Zender interferometer. Phase delay is achieved through light propagation across a fluid-air interface (meniscus). The effect of meniscus curvature on the device transmission is considered using the three-dimensional beam propagation method and shown to be an important device parameter. We engineer the meniscus curvature using monomer surface chemistry, rendering it flat, and find that the experimental response corresponds well with simulation. The device has a resonance at 1.3 mum with a 25 dB extinction ratio; the latter can be adjusted by shifting the meniscus position. (C) 2005 American Institute of Physics.
