Design a system to transfer alternating electric current using six channels of laser as an embedding and transmitting source

Abstract This study introduces a novel approach to transmit alternating electric current through the air utilizing six optical channels LASER setup at 632 nm wavelength. Unlike traditional methods, this approach employs direct modulation within the laser to modulate the alternating current (AC) on an optical wave, enabling efficient transmission over a distance of 15 m. Experimental results reveal a measurable decrease in optical power at the utilized wavelength, providing insights into the system’s performance. Through practical analysis utilizing the EasyEDA tool, the various examined factors, including voltage and current in both transmitter and receiver circuits, contributed to the system’s design. Notably, the system is uniquely tailored for transmitting optical signals using single-phase AC, offering a cost-effective and straightforward circuit implementation with precise control. Despite encountered challenges such as coupling loss, this approach demonstrates promising benefits, underscoring its potential for applications demanding efficient and affordable optical signal transmission.
