Abstract :
An energy efficient and transparent platform for optical wireless networks is proposed based on a novel reversely modulated optical single sideband scheme (RM-OSSB). This scheme is based on a parallel Mach-Zehnder modulator (P-MZM). The bandwidth limitation from electrical and optical components is overcome by down-conversion without electrical mixer, data format compatibility, and dispersion-free. It makes such scheme suitable for a universal platform. Moreover, the modulation power efficiency (MPE) of RM-OSSB can be improved. A theoretical model of RM-OSSB is built up for performance analysis. Both numerical simulations and experimental results match well with our theoretical model. Based on RM-OSSB scheme, a 58GHz full duplex RoF system is experimentally demonstrated. The 2.9Gb/s on-off keying (OOK) signals carried by 58GHz mm-wave is successfully delivered over 50km SMF with negligible power penalty.
