Abstract :
The authors have developed a novel optical waveform measurement technique that measures the waveforms of a randomly modulated optical signal with subpicosecond resolution by using sum-frequency optical sampling and digital processing. With this method, the eye diagram of 10 Gbit/s optical signal is successfully measured with 0.9 ps temporal resolution and 24 dB signal-to-noise ratio
