III-Nitride Semiconductor Photonic Nanocavities on Silicon

Ian Michael Rousseau

Optical nanocavities enhance light-matter interaction due to their high quality factors (Q) and small modal volumes (V). The control of light-matter interaction lies at the heart of potential applications for integrated optical circuits, including optical ...

On the physics of multimode polaritons

Claudéric Ouellet-Plamondon

This thesis is devoted to the study of microcavity polariton systems, in which the strong coupling occurs between more than one exciton or photon modes i.e. multimode polaritons. The first part of this work states the theoretical background of light-matter ...

Quantum optomechanics at room temperature

Hendrik Schütz

Why are classical theories often sufficient to describe the physics of our world even though everything around us is entirely composed of microscopic quantum systems? The boundary between these two fundamentally dissimilar theories remains an unsolved prob ...

Multi-triplet bound states and finite-temperature dynamics in highly frustrated quantum spin ladders

Frédéric Mila, Bruce Normand

Low-dimensional quantum magnets at finite temperatures present a complex interplay of quantum and thermal fluctuation effects in a restricted phase space. While some information about dynamical response functions is available from theoretical studies of th ...

Excitonic Diffusion in InGaN/GaN Core–Shell Nanowires

Hua Zhang, Jean-Daniel Ganière, Gwénolé Jean Jacopin, Mehran Shahmohammadi

We report on the direct observation of the diffusion of carriers in graded InGaN/GaN quantum wells in a nanowire. By probing the local dynamics at the nanoscale, along the wire for different temperatures between 4 and 250 K, we conclude that this diffusion ...

State-to-state scattering of CH₄ from Ni(111) and Gr/Ni(111)

Maarten Eduard van Reijzen

In this thesis, I describe the design and implementation of the first state-to-state surface scattering experiments for methane from clean single crystalline surfaces in ultrahigh vacuum. The experiments use infrared laser pumping to prepare the incident C ...

Multiple polariton modes originating from the coupling of quantum wells in planar microcavity

Benoît Marie Joseph Deveaud, Daniel Oberli, Fauzia Jabeen, Claudéric Ouellet-Plamondon, Grégory Chilpéric Sallen

We report on the observation of multiple polariton modes, originating from an electronic coupling between quantum wells inside a planar microcavity. A series of excitonic transitions are measured for a bare quantum well stack and are precisely identified t ...

Optical and transport properties of GaN/(Al,Ga)N heterostructures in prospect of infrared unipolar devices

Etienne François Olivier Giraud

Over the past decade, a growing interest appeared for III-nitride semiconductors, in view of their potential applications in intersubband (ISB) devices. If these materials are nowadays famous, particularly for having revolutionized domestic lighting thanks ...
