Light self-confinement via second harmonic generation in a 2D nonlinear photonic crystal waveguide
2007
Spatial solitary waves induced by quadratic nonlinearities have been the subject of many theoretical and experimental investigations in the last decade, with extensive studies being devoted to soliton formation in 1D nonlinear photonic crystals (NPC) such as PPLN (periodically poled LiNbO3). Here we present results on a new class of (1 + 1)D spatial solitary waves, the first examples of quadratic self-confinement in a 2D NPC.
Effetti trasversi nella propagazione di fasci ottici in vetri ad alto indice
2008
We investigate beam propagation in a novel Heavy Metal Oxide glass, reporting near infrared beam self-confinement and solitons, filamentation, interactions and conical emission at picoseconds and discussing them with the aid of a model.
