Résumé
Following the demonstration of polariton lasing in GaN ridge polariton lasers [1,2], the polaritonic analog to conventional semiconductor diode lasers, we here analyse and model the laser dynamics in the interesting case of waveguide polaritons. The laser cavities are GaN etched ridge structures with DBRs operating under strong coupling [3] up to 300K with a 66 ± 10 meV Rabi splitting (Fig. 1(a,b)). They are optically pumped with a line-shaped spot, resonantly pumping the exciton reservoir.
