Abstract: An apparatus and method for controlling a multicarrier light source generator are provided. The apparatus includes N-light source input units configured to input light sources to a multicarrier light source generator that generates multicarrier light sources at a frequency interval of F [Hz], and a control unit configured to adjust the frequency interval of the multicarrier light sources generated from the multicarrier light source generator, by adjusting a frequency interval between the light sources input from the N-light source input unit as F/N [Hz].
