An optical pulse train generator 10 includes beat light generation means 11 for generating a beat light 21 having a predetermined repeated frequency, a highly nonlinear fiber 12 for generating a pulse train 22 formed by adding a side mode to the beat light 21 by a four-wave mixing (FWM), and a band pass filter (BPF) 13 for adjusting a power balance of the side mode of the pulse train 22 so as to shape the frequency spectrum.
