Abstract

In order to solve the energy supply problem of the perception terminal of the internet of things in underwater environment, the multifunctional photoelectric characteristics of gallium nitride quantum well diode and compatible manufacturing process are utilized to integrate energy, lighting, communication and perception components on the same gallium nitride chip, and realize interconnection among the devices, so as to prepare gallium nitride energy communication and perception integrated chip. Experiments of visible light wireless energy transmission and communication are carried out on the chip. The experimental results show that the chip can absorb external optical pulse signal and generate stable signal output, and the signal transmission rate can reach 1 Mb/s, which has the potential of relay communication. The chip can also realize energy acquisition and signal communication in underwater environment.
