摘要:

使用深刻的干涉哲学弱值放大,我们提出了一个简单的,一般的和强大的偏振方法的放大和量化的小幅度的所有可能的偏振各向异性效应在一个单一的实验实施例。该方法是通过在弱各向异性效应的存在下,在Mach-Zehnder干涉仪中引入光的偏振自由度和路径自由度之间的弱耦合来实验实现的。不同偏振各向异性效应的实部和虚部弱值放大表现为干涉仪出口处相关斯托克斯矢量元素的特征变化,其遵循庞加莱球中的正交轨迹。概念验证实验表明,使用该方案,人们可以忠实地提取和量化的各向异性参数是小于一个大的弱值放大因子的传统偏振计的一个给定的斯托克斯参数的测量的典型灵敏度。这为研究各种基本光学效应、材料表征和精密计量提供了样品测量弱值偏振计的可能性。

英文摘要:

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.
