Crossing of the branch cut: the topological origin of a universal 2π-phase retardation in non-Hermitian metasurfaces
Rémi Colom, Elena Mikheeva, Karim Achouri +5
Full wavefront control by photonic components requires that the spatial phase modulation on an incoming optical beam ranges from 0 to 2π. Because of their radiative coupling to the…
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…
Nickel oxide-based heterostructures with large band offsets
Robert Karsthof, Holger von Wenckstern, Jesus Zuniga-Perez +2
We present research results on the electronic transport in heterostructures based on p-type nickel oxide (NiO) with the n-type oxide semiconductors zinc oxide (ZnO) and cadmium oxi…
Competition between horizontal and vertical polariton lasing in planar microcavities
O. Jamadi, F. Reveret, D. Solnyshkov +11
Planar microcavities filled with active materials containing excitonic resonances host radiative exciton-polariton (polariton) modes with in-plane wave vectors within the light con…
Edge-emitting polariton laser and amplifier based on a ZnO waveguide
O. Jamadi, F. Reveret, P. Disseix +10
We demonstrate edge-emitting exciton-polariton (polariton) lasing from 5 to 300 K and amplification of non-radiative guided polariton modes within ZnO waveguides. The mode dispersi…
Polariton condensation phase diagram in wide bandgap planar microcavities: GaN versus ZnO
O. Jamadi, F. Réveret, E. Mallet +12
GaN and ZnO microcavities have been grown on patterned silicon substrate. Thanks to a common platform these microcavities share similar photonic properties with large quality facto…
Interplay between tightly focused excitation and ballistic propagation of polariton condensates in a ZnO microcavity
Rereao Hahe, Christelle Brimont, Pierre Valvin +7
The formation and propagation of a polariton condensate under tightly focused excitation is investigated in a ZnO microcavity both experimentally and theoretically. 2D near-field a…
Patterned silicon substrates: a common platform for room temperature GaN and ZnO polariton lasers
J. Zuniga-Perez, E. Mallet, R. Hahe +14
A new platform for fabricating polariton lasers operating at room temperature is introduced: nitride-based distributed Bragg reflectors epitaxially grown on patterned silicon subst…
Strain evolution in GaN Nanowires: from free-surface objects to coalesced templates
M. Hugues, P. A. Shields, F. Sacconi +7
Top-down fabricated GaN nanowires, 250 nm in diameter and with various heights, have been used to experimentally determine the evolution of strain along the vertical direction of 1…
ZnO-Based Polariton Laser Operating at Room Temperature: From Excitonic to Photonic Condensate
Feng Li, Laurent Orosz, Olfa Kamoun +13
A laser threshold is determined by the gain condition, which has been progressively reduced by the use of heterostructures and of quantum confinement. The polariton laser is the ul…

L. Orosz, F. Réveret, S. Bouchoule +11
In order to achieve polariton lasing at room temperature, a new fabrication methodology for planar microcavities is proposed: a ZnO-based microcavity in which the active region is…
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…
