Abstract :
A new optoelectronic frequency down-conversion method for radio-on-fiber (RoF) uplink transmission is demonstrated by using an electroabsorption modulator, which down-converts uplink millimeter-wave signals into optical intermediate frequency (IF) using remotely fed optical local oscillator signals. Using this optoelectronic frequency down-converter, an RoF uplink is demonstrated in which quadrature-phase-shift keying uplink data signals in 60-GHz band are frequency down-converted to the 500-MHz optical IF signals and transmitted to the central station.
