vortex beams

The vortex beams tag on WindowsForum.com covers discussions about terahertz vortex beam generation and shaping, particularly recent advances in semiconductor platforms. The tagged content highlights a new electrically pumped, monolithically integrated device that generates, guides, and shapes terahertz vortex beams on a single chip, using an on-chip fork grating to convert a guided wave into a high-purity vortex output. This approach eliminates the need for bulky external optics, bringing compact terahertz systems closer to practical use. The discussion focuses on the technical details of the device, its potential applications in areas like communications and imaging, and the broader implications for structured light technology.
