Researchers Structure Light with Two Independent Orbital Angular Momenta

Facebook X LinkedIn Email
LOS ANGELES, Aug. 26, 2020 — Researchers at the University of Southern California (USC) have combined twisted light and optical frequency combs to produce a new, dynamic light structure. The discovery has potential to advance understanding of light generation and propagation, and could benefit sensing, imaging, smart manufacturing, and metrology. The discovery stems from the intersection of two distinct research paths. The Optical Communications Lab at USC had been separately researching twisted light beams and frequency combs. The merger occurred when researcher Zhe Zhao considered the potential effects of combining...Read full article
