We have proposed a novel radio over fiber scheme to generate frequency sextuple millimeter wave to reduce system cost at central office(CO) by using one optical modulator. In this scheme, by adjusting the proper DC bias and RF power in CO, the optical millimeter-wave(mm-wave) carriers are generated with six times frequency of the local oscillator(LO) signal using one LiNbO3 Mach-Zehnder Modulator(LN-MZM)...
We have experimentally demonstrated a novel transmission system for seamless integration of ROF with centralized lightwave OFDM-WDM-PON based on an integrated external modulator. At the one of two arms of the integrated external modulator, the optical carrier suppression (OCS) is realized to generate 40-GHz optical millimeter-wave (mm-wave) and up-converted baseband data signal as wireless signal...
A novel scheme for simultaneously realizing optical millimeter-wave generation and photonic frequency down-conversion by employing optical phase modulator and sidebands separation technique is proposed and verified by simulation.
