    Surface spontaneous parametric down-conversion is predicted as a consequence of continuity requirements for electric- and magnetic-field amplitudes at a discontinuity of chi(2) nonlinearity. A generalization of the usual two-photon spectral amplitude is suggested to describe this effect. Examples of nonlinear layered structures and periodically poled nonlinear crystals show that surface contributions to spontaneous down-conversion can be important.

    Povrchová spontánní sestupná parametrická frekvencní konverze je predpovezena a vzniká v dusledku podmínek spojitosti amplitud elektrických a magnetických polí na rozhraní s diskontinuitou chi2 nelinearity. Tento efekt je popsán pomocí zobecnených spektrálních dvoufotonových amplitud.
