The development of a thresholdless laser operating above room temperature (RT) is key for
the future replacement of electronics with photonic integrated circuits, enabling an increase …

Optical microcavities allow us to strongly confine light in small mode volumes and with long
photon lifetimes. This confinement significantly enhances the interaction between light and …

We report on the analysis of electroabsorption in thin GaAs/Al 0.3 Ga 0.7 As nanophotonic
waveguides with an embedded p–i–n junction. By measuring the transmission through …

Semiconductor quantum dots in photonic integrated circuits enable scaling quantum‐
information processing to many single photons and quantum‐optical gates. Obtaining high …

We investigate L7 photonic crystal microcavities (PCMs) fabricated by epitaxial re-growth of
GaAs pre-patterned substrates, containing InAs quantum dots. The resulting PCMs show …

In this thesis we present our recent progress towards the creation of complex quantum
photonic circuits. These devices would integrate on the same chip efficient single-photons …

Deterministic quantum emitters able to generate multiphoton entangled states are essential
building blocks for a plethora of quantum information applications. Solidstate spin-photon …

GaAs nanomembranes grown by selective area epitaxy are novel structures. The high
refractive index of GaAs makes them good candidates for nanoantennas. We numerically …

Generating polarization-entangled photon pairs on chip is generally complicated by the
birefringence of waveguides. In this work, we propose a technique that uses waveguide …

Les cristaux photoniques sont des structures périodiques qui présentent des propriétés
dispersives remarquables. Elles permettent de manipuler, filtrer, guider et façonner la …
