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…
From Strong to Weak Coupling Regime in a Single GaN Microwire up to Room Temperature
A. Trichet, F. Médard, J. Zuniga-Perez +2
Large bandgap semiconductor microwires constitute a very advantageous alternative to planar microcavities in the context of room temperature strong coupling regime between exciton…
