We report an optically controlled Fabry-Perot interferometer which uses a liquid crystal light valve (LCLV) for one of the mirrors. The light valve rotates the plane of polarization for light incident on its read side through an angle dependent on the intensity of a write beam incident on its other side. The Fabry-Perot interferometer is constructed using a polarizing cube beam-splitter and a second mirror. The finesse of this Fabry-Perot varies sharply with the rotation angle introduced by the LCLV. The dependence of this rotation angle on the incident write beam intensity varies with the frequency of the voltage applied to the LCLV, the bias voltage, and the orientation angle of the LCLV. Experimental performance is examined using a single mode He-Ne laser beam and compares well with theoretical predictions: This device has potential uses in optical computing and optical neural networks.
我们报道了一种光控法布里-珀罗干涉仪，它使用液晶光阀（LCLV）作为其中一面镜子。该光阀会使入射到其读取侧的光的偏振面旋转一个角度，这个角度取决于入射到其另一侧的写入光束的强度。法布里-珀罗干涉仪是用一个偏振立方分束器和另一面镜子构建而成的。这种法布里-珀罗干涉仪的精细度会随着LCLV引入的旋转角度急剧变化。这个旋转角度对入射写入光束强度的依赖关系会随着施加到LCLV上的电压频率、偏置电压以及LCLV的取向角而变化。使用单模氦氖激光束对实验性能进行了检测，检测结果与理论预测结果吻合良好：该器件在光计算和光神经网络方面具有潜在用途。
