Development of an Optical Microscope to Investigate the Nonlinear Optical Properties of Single Quantum Dots and to Train Students

Salamo该奖项为一种仪器的开发提供部分支持，该仪器用于测量空间分辨率优于一纳米的小型受限结构的线性和非线性光学特性。单个量子点的线性和非线性光学行为基于使用干涉无孔扫描显微镜SIAM测量磁化率的实部和虚部。基本概念与更传统的近场扫描光学显微镜NSOM有很大不同。SIAM不是通过小的光纤孔径传输光，而是利用原子力显微镜(AFM)或扫描隧道显微镜(STM)的尖端和待探测表面的散射光。这项活动汇集了三名实验人员和一名理论家，他们在量子和非线性光学以及分子束外延和扫描隧道显微镜方面拥有互补的技能。这些科学家目前正在与六名研究生、三名本科生和三名博士后合作，这些项目将通过这里提出的仪器得到显著增强。这项活动涉及四名教员和12名个人进行研究和研究培训。&amp；&amp；&amp；该仪器的开发预计将对学生的研究和教育体验产生重大影响，并提高探索纳米结构行为的能力。

SalamoThis award provides partial support for the development of an instrument to measure linear and nonlinear optical properties of small confined structures with a spatial resolution better than one nanometer.The linear and nonlinear optical behavior of a single quantum dot is based on measuring the real and imaginary parts of the susceptibility using an interferometric apertureless scanning microscope, SIAM. The basic concept is significantly different from the more conventional near-field scanning optical microscope NSOM. Rather than transmitting light through a small fiber aperture, SIAM makes use of light scattered from the tip of an atomic force microscope (AFM) or a scanning tunneling microscope (STM) and the surface to be probed.This activity brings together three experimentalists and one theorist with complementary skills in quantum and nonlinear optics and in molecular beam epitaxy and scanning tunneling microscopy. These scientists presently work with six graduate students, three undergraduates, and three post doctorals on projects that would be measurably enhanced by the instrument proposed here. This activity involves four faculty and twelve individuals in research and research training.&&&The development of this instrument is expected to significantly impact the research and educational experience of students and advance capability to explore the behavior of nanostructures.
