Abstract :
A flexible, high-speed and power-efficient photonic on-off keying and binary phase shift keying modulated Impulse Radio Ultra-wideband over fiber communication system is proposed and demonstrated. Two UWB pulses with inverted polarities and high spectral efficiency are designed and generated experimentally, showing a good agreement with the FCC regulations. The transmission performance over 20 km optical fiber link for both modulation formats is also evaluated and compared by measuring eye diagrams and the electrical spectra.
