Abstract
An optical waveform shaper comprising a probe light source for generating probe light with a constant amplitude, a signal copier to which input signal light of a signal wavelength and the probe light output from the probe light source is applied and which copies the signal of the input signal light onto the probe light, and an extinction ratio improver for improving the extinction ratio of output light from the signal copier is described.
