Magnetic actuation of paramagnetic liquids for optical beam steering in high-speed optical wireless communications

This study examines paramagnetic liquids for optical beam steering in optical wireless communication (OWC) systems.By employing magnetic actuation, effective optical beam control was achieved for both free-space optics (FSO) and underwater wireless optical communication (UWOC).Experimental findings revealed that dysprosium nitrate provided the highest beam steering angles of 5.99in the X direction and 5.73in the Y direction.Additionally, power loss analysis indicated minimal absorption and scattering for dysprosium nitrate and gadolinium nitrate.The system achieved high-speed data rates of 2.1 Gbps for FSO and 1.9 Gbps for UWOC systems, showcasing the promise of this technology.
