Mode-locking instability and multiple soliton formation in GaN polariton waveguide cavities
O. Bahrova, V. Develay, H. Souissi +10
We study the emergence of multi-soliton regimes in 1D ridge polariton waveguides of two different lengths. We show that by varying the position of the gain, which in out-of-equilib…

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…

Soliton formation in a bound state in the continuum GaN waveguide polariton laser
V. Develay, O. Bahrova, I. Septembre +11
We study polaritonic bound states in the continuum (BIC) created in GaN waveguides. The existence of symmetry-protected BICs is confirmed by the suppression of light emission and t…
