摘要:

利用光的轨道角动量(OAM)是开发光子技术用于未来光通信和高维量子密钥分发(QKD)中的应用的有吸引力的方法。OAM资源的广泛使用面临的一个突出挑战是其有效生成。我们设计了一种新的器件,它可以直接发出一个OAM携带光束。通过在垂直腔面发射激光器(VCSEL)的光阑内制作微尺度螺旋相位板(SPP),将VCSEL发射的线偏振高斯光束高效、高质量地转换为具有特定OAM模式及其叠加态的光束。创新的OAM发射器在基于OAM的光和量子通信领域开辟了新的视野,特别是对于短距离数据互连和量子密钥分发(QKD)。

英文摘要:

Harnessing the Orbital Angular Momentum (OAM) of light is an appealing approach to developing photonic technologies for future applications in optical communications and high- dimensional Quantum Key Distributions (QKD). An outstanding challenge to the widespread uptake of the OAM resource is its efficient generation. We design a new device which can directly emit an OAM-carrying light beam. By fabricating micro-scale Spiral Phase Plates (SPPs) within the aperture of a Vertical-Cavity Surface-Emitting Laser (VCSELs), the linearly polarized Gaussian beam emitted by the VCSEL is converted into a beam carrying specific OAM modes and their superposition states with high efficiency and high beam quality. The innovative OAM emitter opens a new horizon in the field of OAM-based optical and quantum communications, especially for short reach data interconnects and Quantum Key Distribution (QKD).
