Group-velocity-matched multistep cascading in nonlinear photonic crystals

Saltiel, Solomon M.; Kivshar, Yuri S.


We demonstrate that simultaneous phase- and group-velocity-matched cascaded parametric processes can be achieved in two-dimensional quadratic nonlinear photonic crystals by proper matching of noncollinear processes with front tilting of the fundamental pulse. We present examples of cascaded third- and fourth-harmonic generation in a poled LiNbO3 planar structure.
