Cavity Quantum Optics with Radiation Pressure

该实验研究计划旨在通过在光学腔中使用辐射压力效应来产生非经典（例如，压缩和纠缠）光。具体来说，研究人员将使用法布里·佩罗腔的光学非线性，其中一个镜子集成到微机械悬臂中。为了使这种非线性产生非经典光，悬臂梁不仅必须响应准静态辐射压力，而且必须响应辐射压力弹噪声。这将通过使用微加工技术（在研究人员早期的工作中开发）来生产专门为此目的设计的超灵敏悬臂来实现。基于理论文献的估计表明，结合这些悬臂梁的空腔应该能够产生压缩和纠缠光，其性能与现有光源相当，在某些应用中甚至优于现有光源。该计划的更广泛影响涉及学生的教育以及与广泛领域的重叠。本项目由数学与物理科学理事会物理部光学物理项目和材料研究部凝聚态物理项目联合支持。

This experimental research program is directed toward producing nonclassical (e.g., squeezed and entangled) light by using radiation pressure effects in an optical cavity. Specifically, the investigators will use the optical nonlinearity of a Fabry Perot cavity in which one mirror is integrated into a micromechanical cantilever. For this nonlinearity to produce nonclassical light, the cantilever must respond not just to the quasi-static radiation pressure, but also to the radiation pressure shot noise. This will be achieved by using microfabrication techniques (developed in the investigators earlier work) to produce ultrasensitive cantilevers specifically designed for this purpose. Estimates based on the theoretical literature suggest that cavities incorporating these cantilevers should be capable of generating squeezed and entangled light with a performance comparable to, and for some applications superior to, currently available sources. The broader impact of the program involves education of students as well as overlap with a wide range of fields. This project is jointly supported by the Optical Physics program in the Physics Division and the Condensed Matter Physics program in the Division of Materials Research of the Mathematical and Physical Sciences Directorate.
