Visible light wireless transmission based on optical access network using white light‐emitting diode and electroabsorption transceiver

Abstract

Technique to develop active devices by modifying Brillouin gain spectrum, Electron Lett 45 (2009), 637-638.ABSTRACT: We propose the visible light communication (VLC) system based on optical access network using light-emitting diode (LED) and electroabsorption transceiver (EAT). The EAT based on electroabsorption modulator is used as an optical network unit in order to be connected with VLC link based on white LED and photodiode (PD). The proposed architecture is demonstrated experimentally, and its performance is verified through the experimental investigation of quality factor and eye pattern of 5 Mbps baseband data. The variation of performance is shown depending on both the existence of the ambient light and the distance between the LED array and PD. A total of 5 Mbps downlink and uplink transmission is verified through 23.2-km single-mode fiber and wireless channel experimentally.

“…The other merits is to possible transmitting information in broadband, is higher security, do not harm human beings, to do not possible cross radio frequency (RF) band and is no frequency permission and fee [6]. The dual function of LED, for lighting and communication, emerges many new and interesting applications [7]. To develop VLC system as a commercial wireless communication network, it is important that the VLC link is connected with the existing optical access network efficiently [7].…”
