Planar microcavities filled with active materials containing excitonic resonances host radiative exciton-polariton (polariton) modes with in-plane wave vectors within the light cone. They also host at least one mode that is guided in the cavity plane by total internal reflection and that is not radiatively coupled to the vacuum modes except...

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...

The physics of gain in interband semiconductor lasers is mostly discussed in terms of population inversion for electrons and holes and the associated Bernard-Durrafourg condition. Due to the reciprocity between the processes of absorption and stimulated emission, one consequence is that lasing action can only be reached in standard ridge lasers...

We present a ridge waveguide polariton laser very similar to standard ridge lasers but, operating on a fundamentally different lasing scheme. The structure consists in a GaN waveguide, operating under strong coupling up to 300K with a 80meV Rabi splitting, and grown by metal-organic vapor phase epitaxy (MOVPE) on c-plane sapphire. Polariton in...
