[OMC6-03] Rapid modulation of the directions of handedness of optical vortices for precise measurements of helical dichroism

*Shun Hashiyada¹, Yoshito Tanaka¹ (1. Research Institute for Electronic Science, Hokkaido University)

We propose and experimentally demonstrate rapid modulation of the directions of handedness of optical vortices carrying orbital angular momentum (OAM) at around 50 kHz. This modulation is achieved through the rapid modulation of those of circularly polarized lights carrying spin angular momentum (SAM), coupled with the SAM-OAM conversion techniques.
