Seminars
Semiconductor Second-Order Nonlinear Nanophotonics
December 17th, 2018 GIUSEPPE LEO Laboratoire MPQ
Université Paris Diderot & CNRS, Paris

The last two years have witnessed a huge progress in dielectric nanophotonics, with a transition from linear and (3) properties to intrinsically stronger (2) effects. In this seminar I will provide an overview of our contribution to this new research domain, from the demonstration of second harmonic generation in nanoantennas to the development of anapole-enhanced nonlinear emission, far-field engineering via grating-assisted or input beam tilt, and transition from single emitters to (2) metasurfaces. Finally I will show our most recent results on all-optical switching of second harmonic generation at the nanoscale, and the photon pair spontaneous parametric generation which now opens subwavelength nonlinear optics to the quantum world.
