摘要

We propose a new scheme to generate polarity-switchable ultrawideband (UWB) Gaussian pulses in the op-ntical domain by use of a phase modulator and a reconﬁgurable asymmetric Mach–Zehnder interferometern(AMZI). In the proposed system, an optical carrier is phase modulated by a Gaussian pulse train and thennsent to a ﬁrst-or second-order AMZI. The system is equivalent to a ﬁrst- or second-order differentiator for thenproduction of Gaussian UWB monocycle or doublet pulses. The polarity of the generated UWB pulses can benswitched by adjusting the phase difference between the two interference components in the AMZI. An ex-nperiment is performed. Gaussian monocycle and doublet pulses with fractional bandwidths of about 177%nand 140% are generated. The polarity switchability of generated UWB pulses is also experimentallynconﬁrmed. © 2009 Optical Society of America
