Čerenkov third-harmonic generation in χ(2) nonlinear photonic crystal Academic Article uri icon


  • We report on the observation of Čerenkov emission of a third-harmonic frequency in a two-dimensional nonlinear photonic crystal, where the second-order nonlinearity X(2) is spatially modulated by the reversal of ferroelectric domains. We analyze both spatial and polarization properties of the emitted radiation and find the results in agreement with our theoretical predictions. © 2011 American Institute of Physics.
