We report on the full control of the optical radiation pressure at fixed photon flux and incident angle by the photon spin. This is done by using transparent chiral liquid crystal droplets that enable a strong coupling between the linear and angular degrees of freedom of a light field. From these results, we anticipate optical sorting of particles with different chirality as well as novel optical trapping and micromanipulation strategies.
我们报告了通过光子自旋对固定光子通量和入射角的光辐射压力的完全控制。这是通过使用透明手性液晶液滴来实现的，这种液滴能够使光场的线性和角自由度之间产生强烈的耦合。基于这些结果，我们预计可以实现具有不同手性的粒子的光学分选，以及新型的光学捕获和微操作策略。
