摘要
从近轴条件下光束轨道角动量理论出发,分析光束的轨道角动量,计算矩形对称的严格周期性阵列光学涡旋的轨道角动量,得每单元格的轨道角动量是确定的,并不与测量轴有关;但是单元格的轨道角动量取决于单元格的选择.分析由三束平面波干涉而得的涡旋阵列光子的轨道角动量,并验证了结论.

Abstract:
According to the basic theory of the orbital angular momentum (OAM) of light under parax ialcondition,the OAM of the beam is analyzed.The OAM of strict ly periodic arrays of optical vortices w ith rectangular symmetry is investigated.It is shown that the OAM per unit cell depends on the choice of unit cell,which is independent of the choice of measurement ax is.But the OAM of the unit cell depends on the choice of cell.And then the photon.s OAM of vortex array derived form three-beam interference of the plane w aves is analyzed to verify the conclusions.
