Electric field characterization for phase-Modulated signals using measured spectrogram
The complex-value electric field of a periodic phase-modulated optical signal is retrieved from the spectrogram/sonogram that is measured by a fast photodiode followed a tunable narrow-band optical filter. With an initial guess from the craters and ridges of the spectrogram, the numerical algorithm...

| description | The complex-value electric field of a periodic phase-modulated optical signal is retrieved from the spectrogram/sonogram that is measured by a fast photodiode followed a tunable narrow-band optical filter. With an initial guess from the craters and ridges of the spectrogram, the numerical algorithm converges very fast to a mean-square error less than 1%. |
