Abstract
We demonstrate a full-duplex WDM millimeter-wave-band radio-on-fiber (RoF) system using a supercontinuum (SC) light source. For downlink transmission, the periodic nature of arrayed waveguide grating, where the period is free spectral range, is used for utilizing the full bandwidth of the SC light source. Half of the SC output modes are used for uplink transmission with photonic downconversion. These techniques are effective to use a wealth of optical frequency resources from the SC light source. Two-channel downlink and one-channel uplink 60-GHz band RoF signals were simultaneously transmitted over 25-km standard single-mode fiber with error-free and no noticeable power penalty.
