It is extremely challenging to control the phase of light at will in free space. Here, Pancharatnam-Berry-phase-enabled, tunable phase control of free-space light is experimentally demonstrated in an ultrathin flexible dispersion-free metadevice. This metadevice enables the broadband conversion of linearly polarized light into any desired output polarization.
在自由空间中随心所欲地控制光的相位极具挑战性。在这里，实验演示了在超薄柔性无弥散超构材料中基于潘查拉纳姆- Berry 相位实现的、可调谐的自由空间光相控。这种超构材料可实现宽带线性偏振光到任意所需输出偏振的转换。
