半导体纳米线光学模中横自旋的出现

Emergence of transverse spin in optical modes of semiconductor nanowires

M. H. Alizadeh, Bjorn M. Reinhard

摘要:

光的横向自旋角动量最近受到了极大的关注,因为它为控制光-物质相互作用增加了一个新的自由度。在这项工作中,我们证明了半导体纳米线的弱导模的横向自旋角动量的产生。这些模式的倏逝场与横向性条件相结合,严格地解释了横向自旋角动量的发生。半导体纳米线中光模的自旋特性在包括手性光捕获、量子信息处理和纳米光子电路在内的一系列新的应用中具有重要的意义。

英文摘要:

The transverse spin angular momentum of light has recently received tremendous attention as it adds a new degree of freedom for controlling light-matter interactions. In this work we demonstrate the generation of transverse spin angular momentum by the weakly-guided mode of semiconductor nanowires. The evanescent field of these modes in combination with the transversality condition rigorously accounts for the occurrence of transverse spin angular momentum. The intriguing and nontrivial spin properties of optical modes in semiconductor nanowires are of high interest for a broad range of new applications including chiral optical trapping, quantum information processing, and nanophotonic circuitry.
