Abstract

Full-dimensional spatial light modulation requires simultaneous, arbitrary, and independent manipulation of the spatial phase, amplitude, and polarization. This is crucial for leveraging the complete physical dimension resources of light. However, full-dimensional metamodulation can be challenging due to the need for multiple independent control factors. To address this challenge, here we propose parallel-tasking metasurfaces to enable full-dimensional spatial light metamodulation based fully on the geometric-phase concept. Indeed, the meta-atoms are divided into several subphases, each of which serves as an independent control factor to manipulate light phase, amplitude, and polarization through geometric phase, interference, and orthogonal polarization superposition, respectively. Therefore, the macroscopic group of meta-atoms leads to metasurfaces that can achieve broadband full-dimensional spatial light metamodulation, as demonstrated by various types of structured light generation. This approach paves the way to future wide applications of light manipulation enabled by full-dimensional spatial light metamodulation.

全维几何相位空间光元调制。

全维空间光调制要求同时、任意和独立地操纵空间相位、振幅和偏振。这对于利用光的完整物理维度资源至关重要。然而，由于需要多个独立的控制因素，全维元调制可能具有挑战性。为了应对这一挑战，我们在此提出了平行任务元表面，以实现完全基于几何相位概念的全维空间光元调制。事实上，元原子被分为多个子相位，每个子相位都是一个独立的控制因子，分别通过几何相位、干涉和正交偏振叠加来操纵光的相位、振幅和偏振。因此，宏观上的元原子组导致元表面可以实现宽带全维空间光元调制，这一点已在各种结构光生成中得到证实。这种方法为未来通过全维空间光元调制实现光操纵的广泛应用铺平了道路。
