TORRES-CISNEROS, M. et al. Conversión paramétrica en un cristal fotónico no-lineal. Rev. mex. fis. [online]. 2005, vol.51, n.3, pp.258-264. ISSN 0035-001X.

In this work we present a novel coherent source of millimeter wavelength waves based on parametric down-conversion in an one-dimensional photonic crystal. Our proposal is based either on the band edge or on defect-mode field enhancement phenomena near a photonic band gap. The numerical results have been showed that a wide range of intensities and bandwidths of coherent radiation can be obtained as we vary either the number periods or the refraction index contrast between layers of the crystal array.
