| Abstract: | The spectra of two photon generation in the process of spontaneous parametric down conversion are studied in a waveguide containing the nonlinear segments with the spatial chirp. Three photon parametric interaction is investigated for the waveguide containing only a spatial fundamental mode. The peculiarities of spectra broadening of photon pair in the chirped waveguide are studied. |
