Abstract :
We demonstrate a method of photonic frequency upconversion useful in radio-over-fiber systems, which is based on Brillouin selective amplification. One of the optical sidebands generated from the applied radio-frequency carrier at 10.831GHz is selected and amplified by Brillouin gain. By carrying the 1-GHz intermediate-frequency (IF) signal on the optical carrier and beating them with the amplified sideband, the IF signal of 1 GHz is upconverted to 11.831 GHz. This scheme can also be applied to the IF signal with bandwidth larger than the Brillouin gain bandwidth. The upconverted 11.831-GHz signal has the phase noise of -83.3dBc/Hz at 10-kHz offset. Also, the proposed upconversion scheme shows the spurious-free dynamic range of 89.5 dBmiddotHz2/3
