论文摘要
引入了矩阵表示，用于固定光束样的光场，该电场允许同时处理轨道角动量（OAM）和空间相干的二阶状态。该相干-OAM矩阵是在笛卡尔极化基础上或相干旋转角动量（SAM）基质的2 x 2梁相干偏振矩阵的对应物。讨论了相干-OAM矩阵的一般特性，然后将相干-SAM-OAM矩阵作为统一实体引入，用于以任何相干，自旋和轨道角动量状态处理光束。
A matrix representation is introduced for stationary beam-like light fields that allows for simultaneous treatment of the orbital angular momentum (OAM) and the second-order state of spatial coherence. This Coherence-OAM matrix is a counterpart of the 2 x 2 beam Coherence-polarization matrix in a Cartesian polarization basis or Coherence-spin angular momentum (SAM) matrix in a circular polarization basis. The general properties of the Coherence-OAM matrix are discussed and then the Coherence-SAM-OAM matrix is introduced as a unifying entity for treating beams with any coherence, spin and orbital angular momentum states.
