Down Conversion

An all-optical premodulation-free microwave frequency up/down-conversion method is presented based on stimulated Brillouin scattering in optical fibers for bidirection radio-over-fiber systems. Through optical heterodyning between the modulated optical carrier and the Stokes light, the microwave signal of 1.5 GHz is up-converted to 9 and 12 GHz, and the microwave signal of 9 GHz is down-converted to 1.5 GHz. The unexpected microwaves are more than 7 dB suppressed by loading the signal to convert with the optical-carrier-suppressed modulation.
