A Q-band radio-over-fiber (RoF) system for the distribution of uncompressed high-definition (HD) video signal is proposed and demonstrated. To eliminate the fiber dispersion induced RF power fading, which is a serious problem for the Q-band RoF system, a polarization modulator (PolM) based transmitter is applied, by which the peak of the frequency response of the fiber link can be shifted to any desired...
A simple, compact, cost-effective post-phase correction method for stable fiber transfer of RF signal is proposed and demonstrated. By employing only one LO source and two frequency mixers, a RF signal is transmitted to the local station with very small phase jitter. An experiment is performed. When a 6-GHz RF signal is delivered through a 20-km SMF, effective cancellation of the phase jitter induced...
A novel technique to generate and distribute UWB signals over optical fiber that is insensitive to fiber dispersion is proposed and demonstrated. The entire system is equivalent to a photonic microwave bandpass filter with a constant frequency response for a different distribution distance. The proposed system is evaluated by a numerical simulation and verified by an experiment. The dispersion insensitivity...
We propose and demonstrate a simple and novel method to generate a quasi-single-sideband (QSSB) optical ultra-wideband (UWB) signal using a dual-drive Mach-Zehnder modulator. To evaluate the transmission performance of the generated QSSB UWB signal, an analytical model is developed with the evolution of the waveforms and the spectra with the transmission distance studied. The theoretical analysis...
