Time-resolved dynamics of GaN waveguide polaritons
Loïc Méchin, François Médard, Joël Leymarie +4
We implement a new experimental approach to directly measure the lifetime of guided polaritons arising from the strong-coupling of GaN excitons and the guided photonic modes of a s…
Effects of the built-in electric field on free and bound excitons in a polar GaN/AlGaN/GaN based heterostructure
Loïc Méchin, François Médard, Joël Leymarie +4
Low-temperature luminescence spectra reveal the presence of two independant populations of GaN excitons within a heterostructure in which a thick (…
Experimental demonstration of a Two-Dimensional Hole Gas (2DHG) in a GaN/AlGaN/GaN based heterostructure by optical spectroscopy
Loïc Méchin, François Médard, Joël Leymarie +5
The polarization discontinuity across interfaces in polar nitride-based heterostructures can lead to the formation of two-dimensional electron and hole gases. In the past, the obse…
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.…
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…
