Optical waveform monitor apparatus and oscilloscope
A measured optical pulse and a sampling optical pulse having different wavelengths are input to a nonlinear optical effect, that is, (i) a nonlinear optical medium generating four optical wave mixing or three optical wave mixing, and the optical intensity of the wavelength converted light generated by the four optical wave mixing or four optical wave mixing generated in a common portion in time of the two optical pulses is detected, thereby observing the waveform of a measured light, or (ii) a nonlinear optical medium generating mutual phase modulation which generates mutual phase modulation, and the optical intensity of converted light switched using a phase shift by mutual phase modulation generated in a common portion in time is detected, thereby observing the waveform of measured light.
