Open AccessWe investigate theoretically the Čerenkov-type second-harmonic generation in two-dimensional bulk nonlinear photonic crystal with longitudinal modulation of the χ(2) nonlinearity. We show that in this scheme the Čerenkov ...
Theoretical study of Cerenkov-type second-harmonic generation in periodically poled ferroelectric crystals Sheng, Yan; Kong, Qian; Roppo, Vito; Kalinowski, K.; Wang, Qi; Cojocaru, Crina; Krolikowski, W. (2012-03)
Open AccessWe study theoretically the Čerenkov-type second-harmonic generation by a Gaussian beam in quadratic nonlinear media with periodically reverted ferroelectric domains. In particular, we consider the role of fundamental ...
