A Q-band radio-over-fiber (RoF) system for transmission of uncompressed high-definition (HD) video signals is proposed and demonstrated. Three key photonic technologies are employed, i.e., the dispersion compensation based on a polarization modulator and a polarizer in the transmitter, the RF carrier extraction based on injection-locked optoelectronic oscillator and the frequency downconversion based on cascaded external modulations in the receiver. A proof-of-concept experiment is carried out. Results show that the proposed system supports 20-km wired and 0.5-m wireless distribution of uncompressed HD video signal. The cooperation of two antennas is also demonstrated, which provides a preliminary demonstration of intelligent RoF system.
