A polarization conversion of a single photon using a semiconductor quantum dot (QD) coupling to a two-mode optical microresonator (MR) is studied. The rotation angle of the polarization vector depends on the orientation of QD axes with respect to MR ones, parameters of the system, and a conversion regime. A nanostructure based on a two-dimensional photonic crystal coupling to a single-electron QD is considered as the possible converter design. It is shown that this structure can also act as a beam splitter and perform the quantum operation NOT on a spatial photon qubit.

光学微谐振器中二维量子点上单光子的偏振转换器

研究了使用耦合到双模光学微谐振器(MR)的半导体量子点(QD)对单光子的偏振转换。极化矢量的旋转角度取决于QD轴相对于MR轴的方向,系统参数以及转换方式。基于二维光子晶体耦合到单电子QD的纳米结构被认为是可能的转换器设计。结果表明,该结构还可以充当分束器,并且不对空间光子量子位执行量子运算。
