摘要

光的模态分解在波导、固体激光器和光纤激光器的模式识别研究中是众所周知的。本文提出了一种基于结构激光束三维空间强度分布的模态分解技术。对不同简并腔中的几何模态进行了分解,得到了特征模态的组成和特征。特别是,我们检索了每个分量的相对相位信息,这对于光通信中的高维数据传输以及量子信息处理中的状态操纵和相干叠加至关重要。该技术可作为一种新兴的光学通信和纠缠光子量子信息处理工具。

Modal decomposition of transverse mode-locked laser beam
Modal decomposition of light is well-known for pattern recognition in studies of waveguides, solid-state lasers as well as fiber lasers. In this letter, we present a modal decomposition technique based on the three-dimensional spatial intensity distribution of structured laser beams. We decompose the geometric modes in the different degenerate cavity and obtain the composition and characteristics of the eigenmodes. In particular, we retrieve the relative phase information of each component which is crucial for high-dimensional data transmission in optical communication and for state manipulation and coherent superposition in quantum information processing. This technology can used as an emerging tool in optical communication and quantum information processing with entangled photons.
