Optical signal fading due to fiber polarization mode dispersion (PMD) has become a primary limiting factor in long haul optical communication links of high data rate of 40 Gb/s and above. Due to the random nature of the fiber PMD, this degradation can not be fully compensated. In this paper, we develop an analytic and intuitive pulse degradation formulism taking into account all major fiber transmission...
We present experimental results of direct extraction of chirp parameter made possible by temporal phase retrieval measurements of ultrafast pulses. Results for a multi-spatial-mode mode-locked semiconductor laser at various bias points are presented. The comparison with the normally used root-mean-square (r.m.s.) chirp parameter reveals that the correlation of the r.m.s. chirp parameter with the actual...
