title: Wavelength-switchable all optical clock recovery at 10Gbit/s based on semiconductor fiber ring laser.
abstract: In this paper, we proposed and demonstrated all-optical clock recovery at 10GHz with switchable wavelengths. Very stable clock signals corresponding to the bit rate of the injection data have been obtained by injecting 10Gbit/s 231-1 PRBS data signals into the ring cavity. Wavelength switching among eight wavelengths is achieved by merely tuning the delay time of the intra-cavity optical delay line. The proposed clock recovery method is experimentally demonstrated to be insensitive to the polarization changes of the input data.
