25-GHz-Spacing Optical-Frequency-Interleaved DWDM 60-GHz-Band Radio-on-Fiber System Using an SC light source and AWGs - Downlink Experiment

摘要

In this paper, we demonstrate 25-GHz-spacing optical-frequency-interleaved DWDM 60-GHz-band radio-on-fiber (RoF) downlink experiment using an supercontinium (SC) light source and arrayed-waveguide gratings (AWGs). Three AWGs are used for multiplexing/demultiplexing the SC modes. In our proposed scheme, filtering response of the AWGs is effectively used for simultaneous suppression of undesired sidebands to avoid the interchannel interference. All the 25-GHz spacing SC modes are used for downlink transmission with photonic up-conversion. Three-channel 60-GHz band RoF signals were simultaneously transmitted over 25-km standard single-mode fiber with error-free and no noticeable power penalty.
