Abstract

In this paper, we experimentally demonstrate message transmission over a commercial optical fiber link modulated by an ultra-wideband (UWB) carrier generated by a chaotic laser diode subject to optical feedback. The laser diode subject to the optical loop feedback is adopted to generate the chaotic UWB carrier. The message, which is generated by a pulse pattern generator, is modulated by the optical intensity modulator. After being transmitted over a 2 km standard single-mode fiber (SSMF), the waveform is recorded by a real-time oscilloscope, in front of which is a photodetector. A message with a bit rate of 2 Gb/s is successfully transmitted over the 2 km SSMF using the chaotic UWB-over-fiber system. In addition, the influences of the amplitude, the bit rate of the message, and the optical power in the SSMF on the transmission quality are separately analyzed in detail. The results presented in this paper are of great importance for UWB communications.
