Research on indoor visible light communication system using LiNbO_3 thin film material as external modulator

摘要

Indoor visible light communication, as an emerging broadband wireless access technology, is currently in the stage of scientific research. This paper focuses on researching fractionally spaced equalizer for indoor visible light communication system, and studies have shown that equalization of indoor visible light communication "multipath interference" to the quality of the communication interference had good inhibitory effect. This paper also proved that the phase conjugate light and transmission light which generated by four wave mixing effect of LiNbO_3 thin film materials have bright quantum entanglement properties. Using visible light communication system with nonlinear film material external modulator, it will be expected to realize indoor quantum communication.
