All-on-chip twisted light modulator for ultrahigh-capacity data processing

该项目旨在通过定制的扭曲光元表面与片上光波导的光子集成来开发一种概念上全新的全片上扭曲光调制器。其目标是用一种紧凑的纳米光子芯片来取代目前体积庞大、速度缓慢、成本高昂的空间光调制器，以产生和检测多种扭曲光模式。项目成果包括光子集成和3D元光学方面的新知识，以及用于扭曲光的新型纳米光子器件，这将扩大扭曲光在全芯片光纤通信和全息显示器中的应用。这种超紧凑、高容量、高效率的扭转光调制器有望在许多光子学应用中产生实际影响。

The project aims to develop a conceptually new all-on-chip twisted light modulator via photonic integration of a customised twisted-light metasurface with on-chip optical waveguides. The goal is to replace current bulky, slow, and costly spatial light modulators by a compact nanophotonic chip for the generation and detection of multiple twisted-light modes. Project outcomes include new knowledge in photonic integration and 3D meta-optics, and novel nanophotonic devices for twisted light, which will expand applications of twisted light for all-on-chip fibre-optic communications and holographic displays. The ultra-compact, high-capacity, efficient twisted-light modulators are expected to have a practical impact on many photonic applications.
