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…
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…
Dirac points annihilation and its obstruction characterized by Euler number and quaternionic charges in kagome lattice
M. Finck, D. Solnyshkov, J. Dubois +1
We investigate the topological phenomenon of Dirac point annihilation and its obstruction in three-band, real symmetric Hamiltonians with time-reversal symmetry, and their relation…
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…
LO-phonon assisted polariton lasing in a ZnO based microcavity
L. Orosz, F. Réveret, F. Médard +13
Polariton relaxation mechanisms are analysed experimentally and theoretically in a ZnO-based polariton laser. A minimum lasing threshold is obtained when the energy difference betw…
