We investigate the influence of a periodic temperature variation over the length of a photonic crystal made of two different nonlinear crystals with quadratic nonlinearity. We derive a set of equations for the propagation of the electromagnetic field in those structures with the use of the multiple scales method. We derive some basic properties of localized solutions and numerically investigate the profiles of these localized modes.
