Quantum Ellisometry

项目编号：ecs -9810355项目负责人：a . V. sergienko题目：量子椭圆偏振分析该项目旨在利用纠缠和正交极化信号和空闲光子对的量子特征来表征光学和光子材料的偏振参数。基于该原理设计的偏振强度干涉仪在阿秒时间尺度上显示出极高的分辨率，并且对穿过样品的光子的吸收或反射非常敏感。这些特点允许使用这种技术作为传统光学椭偏的量子扩展。

Proposal Number: ECS-9810355Principal Investigator: A. V. SergienkoTitle: Quantum EllipsometryAnalysisThe proposal is to develop a new approach to characterize the polarization parameters of optical and photonic materials using quantum feature of entangled and orthogonally polarized signal and idler photon pairs. A polarization intensity interferometer designed based on this principle has shown extremely high resolution in the attosecond time scale, and is sentive to the absorption or reflection of the photons travelling throught the sample. These features allow the use of this technique as a quantum extension of conventional optical ellipsometry.
