ABSTRACT:
A waveform converter includes a transmission-type InGaAsP electroabsorption optical modulator 10 using the Franz-Keldysh effect. Continuous light (probe light) 12 as a target of wavelength conversion is fed to an end surface 10a of the optical modulator 10 while a constant voltage of 3 V is applied to the optical modulator 10. An optical circulator 14 is supplied with original signal light (signal light to be waveform-converted) 16 through its terminal A, and delivers it from the terminal B thereof to another end surface 10b of the optical modulator 10. The optical modulator 10 gives a loss to the probe light 12 according to the intensity of the original signal light 16 and makes the waveform of the probe light 12 to be substantially the same as the original signal light. The probe light waveform-converted by the optical modulator 10 and output from the end surface 10b is fed to a terminal B of an optical circulator 14 as a waveform-converted light 18 and output from its terminal C.
