Electrostatic modulation of excitonic fluid in GaN/AlGaN quantum wells by deposition of few-layered graphene and nickel/gold films
R. Aristegui, P. Lefebvre, C. Brimont +9
Excitons hosted by GaN/(Al,Ga)N quantum wells (QWs) are spatially indirect due to the giant built-in electric field that separates electrons and holes along the growth direction. T…
Electrical control of excitons in GaN/(Al,Ga)N quantum wells
R. Aristegui, F. Chiaruttini, B. Jouault +7
A giant built-in electric field in the growth direction makes excitons in wide GaN/(Al, Ga)N quantum wells spatially indirect even in the absence of any external bias. Significant…
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…
Complexity of dipolar exciton Mott transition in GaN/(AlGa)N nanostructures
F. Chiaruttini, T. Guillet, C. Brimont +6
The Mott transition from a dipolar excitonic liquid to an electron-hole plasma is demonstrated in a wide GaN/(Al,Ga)N quantum well at K by means of spatially-resolved magneto-…
Analysis of low-threshold optically pumped III-nitride microdisk lasers
Farsane Tabataba-Vakili, Christelle Brimont, Blandine Alloing +11
Low-threshold lasing under pulsed optical pumping is demonstrated at room temperature for III-nitride microdisks with InGaN/GaN quantum wells on Si in the blue spectral range. Thre…
Monolithic integration of ultraviolet microdisk lasers into photonic circuits in a III-nitride-on-silicon platform
Farsane Tabataba-Vakili, Blandine Alloing, Benjamin Damilano +12
Ultraviolet microdisk lasers are integrated monolithically into photonic circuits using a III-nitride on silicon platform with gallium nitride (GaN) as the main waveguiding layer.…
