论文摘要
我们提出了一个将等离子体增强的极化单光子引导到光学纳米线（ONW）引导模式的系统。结果表明，在存在金纳米棒二聚体（GNRD）的情况下，可以强烈增强量子发射器（QE）的自发发射特性，从而导致高度极化和明亮的单个光子的发射。我们已经计算出，在ONW的指导模式下，高purcell系数为279，耦合效率为11％，单个光子的极化程度（DOP）高达99.57％，通过将QE适当地放置在GNRD系统的优化位置上。该提出的混合量子系统可以与光纤网络融为一体，为可能的量子信息处理和量子加密应用打开了大门。
We propose a system for guiding plasmon-enhanced polarized single photons into optical nanowire (ONW) guided modes. It is shown that spontaneous emission properties of quantum emitters (QEs) can be strongly enhanced in the presence of gold nanorod dimer (GNRD) leading to the emission of highly polarized and bright single photons. We have calculated that a high Purcell factor of 279, coupling efficiency of 11 %, and degree of polarization (DOP) of single photons is estimated to be as high as 99.57% in the guided modes of ONW by suitably placing a QE on an optimized location of the GNRD system. This proposed hybrid quantum system can be in-line with fiber networks, opening the door for possible quantum information processing and quantum cryptography applications.
