Abstract
To overcome the scarcity of available radio frequency (RF) resource, ultra-wideband (UWB) attracts its attention as one of next generation high-speed radio communication technologies because UWB systems can share the RF band with existing conventional narrowband radio systems. If such UWB signal can be delivered through optical networks without distance limitation, various standalone UWB applications can be networked widely and become available anywhere on demand. In this paper, novel optical transmitter and receiver of millimeter-wave UWB signal are proposed with direct photonic conversion techniques. We experimentally demonstrate the optical detection and regeneration, after 3-m-long transmitted in the air, of the optically generated 24 GHz UWB with the bandwidth of 46 Hz at the data rate of 250 Mb/s
