Paper Abstract

We propose a low cost solution to generate power efficient ultra-wideband (UWB) radio frequency (RF) signal based on the hybrid of optical fiber and RF circuits. In our solution, any return-to-zero (RZ) optical pulse with enough bandwidth is transmitted over optical fiber first, then converted to a power-efficient UWB pulse by an electrical bandpass filter (EBPF) with a passband of 3.1-10.6 GHz. The transmission and modulation of UWB signal is processed in optical domain, whereas the generation of UWB is processed in electrical domain. This solution embodies the advantages of both low-loss long-haul transmission of optical fiber and low-cost mature RF circuits. Both UWB modulations of on-off keying (OOK) and binary phase shift keying (BPSK) are experimentally demonstrated. The impacts of RZ pulsewidth and the EBPF bandwidth on the UWB waveforms are also discussed.
