Abstract:

The birth of nonlinear optics almost coincides with the invention of lasers, which made it possible to generate coherent optical beams characterized by such an intense electric field that their propagation through matter can no longer be described through the linear macroscopic Maxwell equations. Initially, studies focused on harmonic generation in bulk crystals and on soliton propagation in optical fibers. Yet, in the last fifteen years, integrated devices have considerably lowered the power required to observe nonlinear optical phenomena. Thus, somewhat surprisingly, these micro structures have become the key towards an unprecedented control of nonlinear optical phenomena, giving access to new regimes of the light-matter interaction. In this talk I will provide some examples showing the advantage of micro structures over bulk systems in nonlinear optics, from the generation of photon pairs to the first observation strong nonlinear coupling due to induced photon interaction on a SiN chip.
