论文摘要
随着对现代光学元件几乎所有领域的潜在应用的需求不断增长，涡流束的产生引起了极大的兴趣。基于由电流晶体制成的平板，我们提出了一种电控制方法，以生成以pockel效应辅助的涡流束。与传统方法相比，我们的方法可以灵活地调整生成的光学涡流束的波长和拓扑电荷。我们模拟了从平板传输的光束的传播，并研究了传输光束的轨道 - 角摩肌（OAM）模板光谱。 OAM模式光谱与仿真结果一致。所提出的方法提高了光学涡流束的产生的灵活性，可能会在光学通信和光学操作中获得更大的潜在应用。
With the increasing demand for potential applications in almost all fields in modern optics, the generation of vortex beams has attracted significant interest. Based on a flat plate made of electro-optical crystals, we propose an electrically controlling method to generate vortex beams assisted by the Pockels effect. Compared with traditional methods, our method allows flexibly tuning the wavelength and topological charge of the generated optical vortex beams. We simulate the propagation of optical beams transmitted from the flat plate and investigate the orbital-angular-momentum(OAM)-mode spectra of the transmitted optical beams. The OAM-mode spectra are in agreement well with the simulation results. The proposed method improves the flexibility of the generation of optical vortex beams, may gain more significant potential applications in optical communication and optical manipulation.
