摘要

针对传统阶梯型高阶螺旋相位板在光纤端面上制作难度大和使用过程中容易损坏的问题，文章提出了一种在光纤端面上制作平面型螺旋相位板的设计方案。这种相位板在不同方位角上高度相同，通过控制不同方位角处的折射率可获得不同的拓扑荷数。文章使用菲涅尔衍射理论对该方案产生的涡旋电场分布及光强分布进行了详细的理论分析，同时采用时域有限差分方法对基模高斯光束通过具有不同拓扑荷数的平面型螺旋相位板后在光纤中的传播过程进行了仿真验证。仿真结果表明，该种光纤端面平面型相位板对于高阶和低阶模式都能产生高质量的涡旋光束，有效克服了传统阶梯型螺旋相位板存在的不足。

Abstract

Traditional high-order stepped spiral phase plate that is difficult to fabricate on the fiber end face and easy to damage during the application. In order to solve these issues

a design scheme of flat spiral phase plate fabricated on the fiber end face is proposed. This kind of phase plate has the same height at different azimuth angles

and different topological charges are obtained by controlling the refractive index at different azimuth angles. The Fresnel diffraction theory is used to conduct a detailed theoretical analysis of the vortex electric field distribution and light intensity distribution generated by this scheme. The finite difference time domain method is used to simulate the propagation process of the fundamental mode Gaussian beam in the fiber after passing through the flat spiral phase plate with different topological charge. The results show that this kind of flat phase plate on fiber end face can generate high-quality vortex beams for both high-order and low-order modes

which effectively overcomes the shortcomings of traditional stepped spiral phase plate.
