      We study nonlinear frequency generation in media with random ferroelectric domain structure. We show that randomness enables one to realize broadband third harmonic generation via cascading of two second order quasi-phase ...

    • Cerenkov third-harmonic generation in chi((2)) nonlinear photonic crystal 

      Sheng, Yan; Wang, Wenjie; Shiloh, Roy; Roppo, Vito; Kong, Y.; Arie, Ady; Krolikowski, W. (2011-06-13)
      Article
      Open Access
      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 chi((2)) is spatially modulated by the reversal of ...
