Characteristic Analysis and Research Progress of Vortex Beam Produced by Optical Microcavity
In recent years, vortex beams have been widely used in optical communication, optical manipulation, imaging, sensing quantum information, and other fields owing to their unique phase structure and the characteristic of carrying orbital angular momentum (OAM). However, these applications must rely on the generation of high-quality vortex beams so that the optical microcavity occupies a very important position in the modern optoelectronic device manufacturing because of its compact structure, high quality factor, small element size, and other advantages. The developed new integrated optical device can emit high-quality vortex beam. The principle, research progress, design schemes, and experimental generation of optical microcavities to generate OAM beams are discussed in this paper. Simultaneously, the performance of existing OAM lasers is analyzed. Finally, the challenges faced by the applications of integrated optical devices and the directions for further improvement are considered.
