      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 ...

    • The effect of domain distribution on second harmonic generation in disordered nonlinear media 

      Roppo, Vito; Saltiel, Salomon M.; Wang, W.; Kalinowski, K.; Trull Silvestre, José Francisco; Cojocaru, Crina; Neshev, Dragomir N.; Krolikowski, Wieslaw; Vilaseca Alavedra, Ramon; Staliunas, Kestutis; Kivshar, Yu. (2009)
      Conference report

      We study theoretically and experimentally the second harmonic generation in nonlinear crystals with random distribution of ferroelectric domains. We show that the specific features of disordered domain structure greatly ...
