摘要: Highly chirped optical UWB pulses with wide spectral widths tend to be distorted by fiber dispersion, which is undesirable for over transmission systems. In this paper, we investigate theoretically and experimentally a method generate in the domain stable chirp-free signals narrow width. The pulse generator consists of polarization modulator (PolM) polarization-maintaining (PMF) based delay line. generated are transmitted 10- or 24-km standard single-mode followed wireless link. Experimental results show that system has good tolerance dispersion.
