Electrically-injected room-temperature waveguide polariton laser

Hassen Souissi, Valentin Develay, Maksym Gromovyi +14

Exciton-polariton lasers are coherent light sources which do not require the population inversion (transparency) condition to be fulfilled. They have been conceptualized at the end…

Localized emission in MoSe monolayers on GaN nanopillars

Abderrahim Lamrani Alaoui, Álvaro Moreno, Maximilian Heithoff +12

Solid-state quantum emitters (QEs) in two-dimensional semiconductors offer compact, chip-compatible sources for quantum photonics. In transition-metal dichalcogenides (TMDs), nanop…

On the importance of Ni-Au-Ga interdiffusion in the formation of a Ni-Au / p-GaN ohmic contact

Jules Duraz, Hassen Souissi, Maksym Gromovyi +12

The Ni-Au-Ga interdiffusion mechanisms taking place during rapid thermal annealing (RTA) under oxygen atmosphere of a Ni-Au/p-GaN contact are investigated by high-resolution transm…

Mode-locked GaN waveguide polariton laser

H. Souissi, M. Gromovyi, I. Septembre +12

So far, exciton-polariton (polariton) lasers were mostly single mode lasers based on microcavities. Despite the large repulsive polariton-polariton interaction, pulsed mode-locked…

Ridge polariton laser: different from a semiconductor edge-emitting laser

H Souissi, M Gromovyi, T Gueye +11

We experimentally demonstrate the difference between a ridge polariton laser, and a conventional edge-emitting ridge laser operating under electron-hole population inversion. The h…

Strong coupling of exciton-polaritons in a bulk GaN planar waveguide: quantifiying the coupling strength

C. Brimont, L. Doyennette, G. Kreyder +12

We investigate the demonstration and quantification of the strong coupling between excitons and guided photons in a GaN slab waveguide. The dispersions of waveguide polaritons are…
