Integer Multiplier for Orbital Angular Momentum of Light using Circular-Sector Transformation
Satoru Takashima, Hirokazu Kobayashi, Katsushi Iwashita
This paper describes an integer multiplier for the orbital angular momentum (OAM) of light through the parallel implementation of multiple circular-sector transformations, whereby…
