Abstract

We propose a novel scheme for simultaneously realizing optical mm-wave generation and remote photonic down-conversion by using optical phase modulator along with sidebands separation technique. In the central office, optical double sideband (DSB) signal is generated by using an optical phase modulator. One sideband of the generated optical DSB signal is filtered out to carry downstream data signal. In the base station, the sideband carried with downstream data beats with part of the optical carrier, thereby generates mm-wave signal. Another sideband along with part of the optical carrier is injected into the second phase modulator to implement photonic frequency down-conversion for uplink signal transmission. We also theoretically show the principle of photonic frequency down-conversion based on the optical phase modulator. By using the scheme, no additional optical local oscillator signal or RF signal is needed because the full advantage of sidebands of the optical DSB signal has been taken.
