Subcarrier demultiplexing using a tunable single resonance microwave photonic filter in radio-over-fiber system

摘要

A method for subcarrier demultiplexing in Radio-over-Fiber system has been proposed and verified experimentally. A continuously tunable single resonance microwave photonic filter using the tunable fiber Mach-Zehnder interferometer (MZI) as the slicing filter, is implemented to realize the demultiplexing. Two subcarriers, one is 2.4GHz representing the wireless LAN signal , the other is 900MHz representing the Cellular signal, can be demultiplexed separately. The proposed approach has been demonstrated both theoretically and experimentally.
