Abstract

We proposed a novel microwave-band radio-over-fiber system with wavelength-division multiplexing (WDM) bus architecture. An electrooptic phase modulator combined with Fiber Bragg Gratings (FBGs) can realize frequency multiplying. Here the FBGs are used to fulfill three main tasks: convert phase modulation into intensity modulation, filter away unwanted optical frequency components, and work as demultiplexers in the WDM radio-over-fiber system. Simulation demonstrates a system capable of multiplying the frequency of differential phase-shift keying (DPSK) modulated signals from 2.7GHz to 5.4GHz (two times), 10.8GHz (four times) and even higher frequency values after transmitting the signals over 0.5 km of polymer optical fiber. Such a RoF system is cost-effective and suitable to install in in-house environment.
