Abstract :
Aiming at the measurement of waveform and phase of optical pulses at 1.55 μm, we construct an optical sampling system that enables sonogram characterization of optical pulses. We demonstrate the measurement of impulse response of an optical bandpass filter as a specific application of the system. The measured intensity and phase responses clearly show the effect of the dispersion slope of the filter.
