论文摘要
使用弱值扩增的深刻干涉哲学，我们提出了一种简单，一般和强大的极化方法，用于在单个实验实施方案中对所有可能的极化各向异性影响的小小的幅度进行扩增和定量。通过在弱各向异性效应的情况下，在马赫德尔干涉仪中引入了光自由度的极化自由度与自由度的自由度之间的弱耦合，从而实现了实验。不同极化各向异性效应的真实和假想的弱值扩增表现为在干涉仪出口端口的相关stokes矢量元件的特征变化，而干涉仪的出口端口则遵循庞加雷球体中正交轨迹的轨迹。概念验证实验证明，使用此方案可以忠实地提取和量化各向异性参数，该参数小于传统偏光仪的给定stokes参数的典型敏感性，这是通过大弱值放大因子的。这打开了测量弱价值偏振仪的样本的可能性，用于研究丰富的基本光学效应以及材料表征和精度计量学。
Using the profound interferometric philosophy of weak value amplification, we propose a simple, general and a robust polarization method for the amplification and quantification of small magnitudes of all possible polarization anisotropy effects in a single experimental embodiment. The approach is experimentally realized by introducing a weak coupling between the polarization degree of freedom of light and the path degree of freedom in a Mach-Zehnder interferometer in the presence of a weak anisotropy effect. Real and imaginary weak value amplifications of different polarization anisotropy effects are manifested as characteristic changes in relevant Stokes vector elements at the exit port of the interferometer, which follow orthogonal trajectories in the Poincare sphere. The proof of concept experiment demonstrates that using this scheme, one can faithfully extract and quantify anisotropy parameter that is smaller than the typical sensitivity of measurement of a given Stokes parameter of a traditional polarimeter by a large weak value amplification factor. This opens up possibility of a sample measuring weak value polarimeter for studying rich variety of fundamental optical effects and for materials characterization and precision metrology.
