2019年10月2日 · Hitherto, owing to these salient properties and optical manipulation technologies, tunable vortex beams have engendered tremendous advanced applications such as optical …

The orbital angular momentum of light (OAM) is the component of angular momentum of a light beam that is dependent on the field spatial distribution, and not on the polarization. OAM can …

2017年3月9日 · Perfect vortex beams are the orbital angular momentum (OAM)-carrying beams with fixed annular intensities, which provide a better source of OAM than traditional...

2025年1月2日 · In this paper, we employ a phase splicing technique to generate a stable vector vortex beam with dual-fractional OAM, and we systematically investigate the focusing and …

5 天之前 · Since the generated beam is a type of structured light beam, the proposed concept can be extended to realize spatially variant vector OAM combs, Laguerre-Gaussian (LG) and …

2024年12月1日 · Here we demonstrate the generation of L P 11 and four degenerate vector mode based on home-made mode selective couplers (MSCs), then two experimental methods to …

2024年10月8日 · In this work, we introduce a swift and efficient identification scheme designed specifically for OAM states in vector beams. This innovative scheme enables the simultaneous …

OAM waves for optical, radio and acoustic communications. For each system we present a complete and accurate review of the generation/detection methods, their application and the

We propose a simple approach to broadband generation of orbital angular momentum (OAM) carrying vector beams based on compact metamaterials. It consists of two concentric rings in …

6 天之前 · Figure 2 shows the ordination of the vector modes (both OAM and LP modes) field distributions such as intensity and phase in the designed PCF. In the corresponding order of …
