We demonstrate a cost effective broadcast signal transmission in a WDM-PON by using directly modulated mutually injected Fabry-Pérot laser diodes (MI F-P LDs) as a low noise broadband light source (BLS). This novel WDM source enables to transmit the 1.25-Gb/s/channel with 100 GHz channel spacing.
At the ubiquitous age, applications of Wireless Personal Area Network (WPAN) technology using LEDs are in progress. However, visible light communication using LED have weakness, which deteriorates performance of communication. To reduce information losses, which is caused by optical noise, such as incandescent lamps, fluorescent lamps, sunbeam etc., proposed channel coding scheme, double binary turbo...
Today, the improved wireless communication technique for increasing demand for the next generation communication system is developed variously to transmit a long distance and high data. Visible light communication (VLC) system uses radiated light of LEDs. However, VLC have weak points which deteriorate performance of communication. Because there is multi-path fading that occurs propagation delay by...
