Abstract

The development of a two-photon source based on the effect of spontaneous four-wave mixing (SFWM) of light involves solving a number of tasks: from choosing a structure of suitable length and nonlinearity to a detailed analysis of dispersion properties. We consider an integrated spiral waveguide made of a composite polymer using optical lithography as a potential photon pair generation scheme. As a result of the analysis of the modes and dispersion properties, it was possible to determine the zero-dispersion wavelengths necessary for the occurrence of the SFWM effect, as well as the main limitations of the wavelength range of the generated two-photon fields.
