The present invention is equipped with: a first shaping unit (20) for subjecting an optical pulse for sampling to at least intensity modulation using an analog signal, and as a result, intensity-modulating the optical pulse for sampling by using an analog signal, and generating a first optical pulse having a spectrum which has a flat intensity in the spectral axis direction; a second shaping unit (30) for subjecting the optical pulse for sampling to spectral shaping, and as a result, generating a second optical pulse having a spectrum which has an intensity that monotonically increases or monotonically decreases in the spectral axis direction; a phase shift unit (26) for shifting the phase of an optical pulse inputted into the first shaping unit (20) or the second shaping unit (30) in a manner such that the phase difference between the first optical pulse and the second optical pulse equals a prescribed phase difference; an interference unit (12) for causing the first optical pulse and the second optical pulse to interfere with one another; and a wavelength demultiplexing unit (14) for separating the optical pulses outputted from the interference unit (12) into a plurality of wavelength bands. |
