Parametric Down Conversion (PDC) is widely used as the source of pairs of single photons in quantum information science. The properties of this nonlinear optical process, however, have to be tailored to generate the desired state. Here we focus on engineering the dispersion properties of the PDC process to generate spatially single-mode and spectrally decorrelated PDC states at telecommunication wavelengths. Periodically poled potassium titanyl phosphate (PPKTP) can provide those required features. Here we present our recent advances in fabrication of such waveguided PDC sources.
