title: Simultaneous type I and type II Čerenkov-phase matched second-harmonic generation in disordered nonlinear photonic structures.
abstract: We observe simultaneous type I and II Čerenkov-phase matched second-harmonic generation in a disordered nonlinear photonic crystal. The mean width of the disordered ferroelectric domains and the laser beam width are adjusted to be on the same length scale. We analyze the polarization properties, emission angles and intensities of each process.
