Spinning multiplexed Laguerre–Gaussian beams
摘要
Multiplexed Laguerre–Gaussian (MLG) beams have garnered significant interest due to their unique properties arising from the superposition of independent Laguerre–Gaussian (LG) beams. Researchers explore MLGs for applications in optical communications, quantum computing, and precise manipulation of trapped particles, offering promising avenues for advancing optical technologies and high-dimensional quantum states. In this study, a straightforward technique for generating and rotating the MLGs has been explored. By introducing an easily controllable additional degree of freedom, rotation of the transverse profile, the data transmission capabilities of MLGs can be enhanced and precise manipulation of trapped particles can be achieved. The proposed approach has been experimentally and computationally validated, and methods for controlling rotation speed, direction, and halting have been provided. The proposed straightforward and easy-to-use technique can enhance the MLG application in various optical fields.
