摘要We propose a scheme to generate ultrawideband (UWB) monocycle pulses using delayed interference of a pi/2 phase-shift keying (PSK) signal. The PSK signal is generated with an optical phase modulator. A fiber-based delay interferometer is used to provide the delay together with a +/-pi/2 phase shift between the signals in its two arms before the interference. The two opposite phase shifts correspond to the generation of a pair of polarity-reversed UWB monocycle pulses. The full width at half maximum of the pulses is similar to 68 ps and the 10 dB fractional bandwidth is 168%. (C) 2011 Optical Society of America
