Abstract
A wavelength-division multiplexed colorless radio-on-fiber (RoF) system based on a reflective semiconductor
optical amplifier (RSOA) is proposed in this paper. This scheme has a colorless and simple base station (BS),
because an RSOA playing the role of amplification and modulation is used at the BS, irrespective of the wavelength.
The spurious-free dynamic range, gain, and noise figure of both the downlink and uplink are presented to verify the
suitability of the scheme for an RoF system. Error-free transmissions for both uplink and downlink wireless signals
of 1.25 Gb/s are demonstrated. From the experimental results using an RF subcarrier of 3 GHz as a wireless signal,
it is held that the performance of this scheme will change only slightly when using a millimeter-wave signal (
> 30 GHz).
