Abstract :
An approach for multiple-frequency millimeter-wave (mm-wave) signal generation is proposed for radio-over-fiber (RoF) systems with multiple base stations (MBSs). Two groups of orthogonally polarized pumps are injected into a semiconductor optical amplifier (SOA), and subsequently, ten new different wavelengths are generated via four-wave mixing (FWM). At the BSs, different wavelengths are filtered out using de-multiplexer and then input to a photo-diode (PD) to generate mm-wave signals with the frequencies of 52-68 GHz which have 2 GHz grid. Simulation results verify that the proposed multiple wavelength conversion enhanced MBS-RoF system can work properly.
