Optimizing doubly-resonant photonic crystal cavity modes for second harmonic generation

Vincenzo Savona, Momchil Minkov

We optimize a photonic crystal slab for the generation of second harmonic. The optimization consists in two steps. In the first step a regular photonic crystal, consisting in a triangular lattice of circular holes in a dielectric slab, is optimized by allo ...

Nonlinear relaxation and selective polychromatic lasing of confined polaritons

Benoît Marie Joseph Deveaud, François Morier-Genoud, Marcia Portella Oberli, Gabriele Grosso, Stéphane Trebaol

Polaritons have often been proposed as promising candidates for the realization of all-optical devices due to the easy manipulation and control of their density and spin. In this paper we present a relaxation mechanism for confined polaritons and its appli ...
