Abstract

The ray-wave geometric beams (RWGBs) are fantastic structured light field with multiple degrees of freedom (DoFs). These DoFs endow countless application prospects for RWGBs in optical communication, quantum entanglement, optical tweezers. Meantime, the intricate orbital angular momentum (OAM) structures and intensity shape brought by these DoFs have caused great difficulty in its sort and limited its application. We propose a new digital holographic method to identify multi-DoFs RWGBs based on the conjugated modulation theory, thus called conjugated modulation identification (CMI). The experiment results indicate that the RWGBs were fully resolved, and the reconstructed correlation degree shows good agreement with the theoretical values. Furthermore, the 8-bit and 16-bit multi-RWGBs shift keying encoding were demonstrated. The signal is well recovered with no error, demonstrating the proposed method with good data transmission performance. Our work reveals wide potential applications of RWGBs in realizing high-speed, high-dimensional time-varying modes multiplexed encoding and high-capacity multi-channel communication.
