Zusammenfassung:A light source includes: a seed light source configured to output incoherent seed light having a predetermined bandwidth; and a booster amplifier that is a semiconductor optical amplifier configured to optically amplify the seed light entered through a first end facet and output the amplified light through a second end facet. The booster amplifier has nL being set, which is a product of a refractive index n and a chip length L, so as to simultaneously suppress relative intensity noise (RIN) and ripple in the amplified light.
