We investigate evolution of multimode quantum light in electro-optical modulator, using semiclassical model of phase modulation process. For the case of monochromatic incoming signal, we consider transformation of its spectrum and calculate statistical properties of each frequency mode. Particularly, we find that for the case of initial coherent state our result is covered by the well-known classical model. While for the case of initially squeezed state we observe single- and multi-mode squeezing in frequency spectrum of modulated light.
