Abstract
In this paper, we studied the properties of two-photon quantum states of light that emerge due to spontaneous parametric downconversion in a nonlinear waveguide with periodically poles structure. The spectral and entangled properties have been studied mainly for photon pairs whose spectra is located in the near-infrared range. We found that it is possible to select the geometric parameters of the structure of a lithium niobate nanowaveguide in such a way that the two-photon quantum state in the near-IR range will have a spectrum width of about 180THz.
