报告摘要:

Coherent radio over fiber (RoF) links have been studied recently for the transmission of high-data-rate wireless signals with increased receiver sensitivity and spectral efficiency. In a coherent RoF link, a transmitter laser source and a receiver laser source (as a local oscillator source) that are not phase locked are used. A coherent RoF link suffers from the performance degradation due to the phase noise and the unstable frequency difference introduced from the transmitter and local oscillator (LO) laser sources. In this talk, solutions to cancel the phase noise and to eliminate the impact from the unstable frequency difference will be discussed. The performance of a few experimentally demonstrated coherent RoF links with improved sensitivity and spectral efficiency will be discussed.
