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 novel photonic frequency downconverter is proposed and demonstrated using a single dual-drive Mach-Zehnder modulator (DMZM). In the proposed scheme, the local oscillator (LO) and radio frequency (RF) signals are sent to the two RF ports of the DMZM, respectively. By biasing the modulator at the minimum transmission point, a downconverted intermediate frequency (IF) signal with the RF and LO components...
A radio over fiber system for transmission of 3-Gb/s uncompressed HD video is proposed and demonstrated. By using a polarization modulator (PolM) in the transmitter, the power fading caused by the dispersion of the optical fiber is effectively reduced. In the receiver, an injection-locked frequency-doubling optoelectronic oscillator (OEO) is employed to simultaneously extract the RF carrier and perform...
