Abstract :
We demonstrate the use of InP/InGaAs heterojunction phototransistors as optoelectronic mixers for bi-directional millimeter-wave band radio-on-fiber systems. For downlink transmission, optically transmitted IF signals are frequency up-converted to millimeter-wave band signals in InP HPT optoelectronic mixer with remotely-fed optical local oscillator (LO) signals. Uplink signals at millimeter-wave band are applied to the base port of InP HPT and frequency down-converted to IF band. Utilizing this proposed scheme, bi-directional radio-on-fiber transmission in 60GHz band is demonstrated.
