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 (…
