1.25 Gbit/s millimetre-wave band wired/wireless radio-over-fibre system based on RSOA using injection-locking effect

A new architecture for a millimetre-wave band radio-over-fibre system is proposed. Both optical carrier suppression and injection locking effect are used to simultaneously generate a 1.25 Gbit/s wired signal and a 63 GHz wireless one. Error-free transmissions (bit error rate of 10^-11) of downlink and uplink data are achieved to verify the proposed scheme. No impact of a downlink data transmission on an uplink one owing to the wavelength reuse is observed. It is checked that there is only the 2 dB power penalty of the uplink owing to the Rayleigh backscattering noise.
