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…
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…
Demonstration of critical coupling in an active III-nitride microdisk photonic circuit on silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +11
On-chip microlaser sources in the blue constitute an important building block for complex integrated photonic circuits on silicon. We have developed photonic circuits operating in…
III-nitride on silicon electrically injected microrings for nanophotonic circuits
Farsane Tabataba-Vakili, Stéphanie Rennesson, Benjamin Damilano +14
Nanophotonic circuits using group III-nitrides on silicon are still lacking one key component: efficient electrical injection. In this paper we demonstrate an electrical injection…
Blue Microlasers Integrated on a Photonic Platform on Silicon
Farsane Tabataba-Vakili, Laetitia Doyennette, Christelle Brimont +12
The main interest of group-III-nitride nanophotonic circuits is the integration of active structures and laser sources. A photonic platform of group-III-nitride microdisk lasers in…
Q factor limitation at short wavelength (around 300 nm) in III-nitride-on-silicon photonic crystal cavities
Farsane Tabataba-Vakili, Iannis Roland, Thi-Mo Tran +10
III-nitride-on-silicon L3 photonic crystal cavities with resonances down to 315 nm and quality factors (Q) up to 1085 at 337 nm have been demonstrated. The reduction of the quality…
A universal description of III-V/Si epitaxial growth processes
I. Lucci, S. Charbonnier, L. Pedesseau +15
Here, we experimentally and theoretically clarify III-V/Si crystal growth processes. Atomically-resolved microscopy shows that mono-domain 3D islands are observed at the early stag…
