— 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(More)
We propose a demultiplexing scheme for a DWDM mm-wave fiber-radio system by optical frequency interleaving. The scheme consists of a Fabry-Perot etalon, an optical circulator and a 2 x N arrayed-waveguide grating, which is designed to steer the input signals with the frequency difference equals to the millimeter-wave carrier frequency into the same output(More)
SUMMARY We propose a coherent optical and radio seamless network concept that allows broadband access without deployment of additional optical fibers within an optical fiber dead zone while enhancing network resilience to disasters. Recently developed radio-over-fiber (RoF) and digital coherent detection technologies can seamlessly convert between optical(More)
