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...

Polaritons in waveguides offer novel potentialities for their application in optoelectronics, based on the concept of the polariton laser. Unlike a conventional semiconductor laser, polariton laser does not require any population inversion in order to stimulate the light emission, which potentially allows the creation of laser components...

Polaritonic waveguides are bringing new potentialities to the field of polaritonics. The low waveguide losses allow for long propagation distances, up to hundreds of microns. In GaAs waveguides at T=4K, the formation of bright temporal solitons was demonstrated [1], as well as the generation of a super-continuum. Wide bandgap materials offer...
