Photonic Transmitter and Receiver of Millimeter-Wave Ultra-Wideband Signal by Direct Photonic Frequency Conversion Techniques

摘要

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 stand-alone UWB applications can be networked widely and become available anywhere on demand.In this paper, novel photonic 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 4 GHz at the data rate of 250 Mb/s.
