“Under Water Communication using Visible Light”

Abstract: Future electric lights will be comprised of visible LEDs (light emitting diode).Visible LED’s with high power output are expected to serve in the next generation of lamps. An indoor visible data transmission system utilizing visible led lights is proposed. In the system, these devices are used not only for illuminating rooms but also for an optical wireless communication system. This system is suitable for private networks such as consumer communication networks. However it remains necessary to investigate the properties of visible LED’s when they are used as optical transmitters. Based on numerical analyses and computer simulations it can be used for indoor optical transmission. Infrared light is already used for communication, such as wireless remote control, IrDA, Infrared wireless LAN, and infrared inter-building communication. However, visible light LEDs are beginning to be used in every home and office, which makes visible light LEDs ideal for ubiquitous data transmitter.
