거대 비선형 응답을 갖는 궤도 각 운동량 모드의 회전제어를 위한 메타표면

Abstract

Nonlinear optical devices that integrated with spin and orbital angular momentum will open new avenues for increasing the capacity for optical information processing. In this work, we present nonlinear metasurfaces based on combining multiple quantum wells with plasmonic nanoantennas to control SAM of light for efficient nonlinear OAM beam generation.
