Phase and Amplitude Responses of Narrow-Band Optical Filter Measured by Microwave Network Analyzer
Hsi-Cheng Wang, Keang-Po Ho
The phase and amplitude responses of a narrow-band optical filter are measured simultaneously using a microwave network analyzer. The measurement is based on an interferometric arr…
On the effect of dispersion on nonlinear phase noise
Keang-Po Ho, Hsi-Cheng Wang
The variance of nonlinear phase noise is analyzed by including the effect of intrachannel cross-phase modulation (IXPM)-induced nonlinear phase noise. Consistent with Ho and Wang […
Simultaneous Amplitude and Phase Measurement for Periodic Optical Signals Using Time-Resolved Optical Filtering
KeangPo Ho, Hsi-Cheng Wang, Hau-Kai Chen +1
Time-resolved optical filtering (TROF) measures the spectrogram or sonogram by a fast photodiode followed a tunable narrowband optical filter. For periodic signal and to match the…
Comparison of Nonlinear Phase Noise and Intrachannel Four-Wave-Mixing for RZ-DPSK Signals in Dispersive Transmission Systems
Keang-Po Ho, Hsi-Cheng Wang
Self-phase modulation induced nonlinear phase noise is reduced with the increase of fiber dispersion but intrachannel four-wave-mixing (IFWM) is increased with dispersion. Both deg…
