| Abstract(in English) | A simple clock extraction method from high speed optical NRZ signals using a π-phase shifted fiber Bragg grating (π-PSFBG) is proposed. The theoretical analysis of the pseudo RZ signal generated by the π-PSFBG show that the proposed method remarkably enhances the clock component. The experimental confirmation of the principle using a trially fabricated device lend support to the theory and the clock-to-modulation components ratio improves 27dB to the original NRZ signal. The computer simulation results also show that the proposed method is able to support high speed optical NRZ signals at 160Gbit/s easily and the deteriotation of the clock-to-modulation component ratio is within 3dB when the wavelength difference between the optical NRZ signal and the null wavelength of the π-PSFBG is within ±0.25nm. |
