Liquid-crystal fork gratings are demonstrated through photopatterning realized on a DMD-based microlithography system. This supplies a new strategy for generating fast switchable, reconfigurable, wavelength-tolerant and polarization-insensitive optical vortices. The technique has great potential in broad fields such as OAM-based quantum computations, optical communications, and micromanipulation.
液晶叉状光栅通过基于 DMD 的微光刻系统实现的光图案化来演示。这为产生快速可切换、可重构、波长容忍和偏振不敏感的光学涡旋提供了一种新策略。该技术在基于轨道角动量的量子计算、光通信和微操纵等广泛领域具有巨大的潜力。
