摘要

我们提出了一种紧凑的Si3N4-Si3N4-SOI光栅耦合器，用于产生光学涡旋光束。通过多种模式输入组合，多层器件可以调谐到OAM状态为±1和±2的光束。

Integrated compact optical orbital angular momentum generator based on multi-layer non-uniform grating coupler

We propose a compact Si3N4-Si3N4-SOI grating coupler for generating optical vortex beams. With various mode input combinations, the multi-layer device can be tuned to emit beam with OAM states of ± 1 and ± 2.
