ABSTRACT

Set of nonstationary truncated equations is solved to calculate spectral density and hence energy density of signal pulse. The pumping pulse is considered to be Gaussian. Dependences of energy density on the characteristic lengths were depicted. It is shownthat the energy density has clearly maxima versus characteristic lengths. In addition, it was observed that the energy density decreases with increase in phase modsulation parameter of idler pulse. In contrast to ordinary nonlinear medium larger values of energy are obtained at the input, but not at the output of metamaterial.

Keywords: nonstationary frequency conversion, group velocity difference, group velocity dispersion, Gaussian pulse, metamaterial, dispersion propagation length, dispersion propaation time.
