title = "Automatic polarization control in optical sampling system",
abstract = "In an optical sampling system for high-speed optical communications, polarization controlling is one of the most important parts of the system, regardless of nonlinear optical sampling or linear optical sampling. A simple method based on variance calculation of sampled data is proposed in this paper to tune the wave plates in a motor-driven polarization controller. In the experiment, an optical sampling system base on SFG in PPLN is carried for a 10Gbit/s or beyond optical data signal. The results demonstrate that, with the proposed method, the error of estimated Q factor from the sampled data is least, and the tuning time of optimized polarization state is less than 30 seconds with the accuracy of ±1°.",
