摘要

我们研究了一种通过扭曲向列（TN）液晶（LC）器件进行光学相位控制的马赫-泽恩德干涉仪。在一个典型的 TN LC 器件中，施加约 5 V 的电压就能获得 π/2 的光旋转状态变化，而电池的厚度仅为几微米。TN 电池被插入马赫-泽恩德干涉仪的一条光路中。当对 LC 电池施加电压时，由于光学干涉状态的变化，我们获得了图案的变化。因此，在弱光条件下可以观察到光子数量的变化。

Quantum optical control experiment using Mach–Zehnder interferometer and twisted nematic liquid crystals

A Mach–Zehnder interferometer with an optical phase control by a twisted nematic (TN) liquid crystal (LC) device was studied. In a typical TN LC device, a change in the optical rotation state of π/2 can be obtained by applying a voltage of about 5 V with a cell thickness of several-micron. The TN cell is inserted into one optical path in the Mach–Zehnder interferometer. We obtained a pattern change when voltage was applied to the LC cell due to the change of the optical interference state. As a result, a change in the number of photons under weak light conditions is observed.
