Nonequilibrium exciton physics in hybrid lead-halide perovskites and anatase titanium dioxide

Tania Palmieri

The strength of the electron-hole interaction in bulk semiconductors is not only determined by the dielectric environment, but also depends on the presence of other quasiparticles - free charge carriers or phonons - that populate the system. In the former ...

Light-Matter Interaction in III-Nitride Waveguides: Propagating Polaritons and Optical Gain

Joachim Armand Simonne Ciers

III-nitride waveguides featuring AlInN claddings and GaN/AlGaN quantum wells (QWs) offer promising perspectives for applications in many fields of short-wavelength photonics. Thanks to their nearly lattice-matched nature, these structures exhibit an excell ...

Manipulation of Bloch surface waves: from subwavelength focusing to nondiffracting beam

Hans Peter Herzig, Myun Sik Kim

We present a different type of electromagnetic surface wave than a surface plasmon polariton (SPP), called Bloch surface wave (BSW). BSWs are sustained by dielectric multilayers, and therefore they do not suffer from dissipation. Their propagation length i ...

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 ...

Propagating Polaritons in III-Nitride Slab Waveguides

Nicolas Grandjean, Jean-François Carlin, Raphaël Butté, Gwénolé Jean Jacopin, Joachim Armand Simonne Ciers

We report on III-nitride waveguides with c-plane GaN/(Al,Ga)N quantum wells in the strong light-matter coupling regime supporting propagating polaritons. They feature a normal-mode splitting as large as 60 meV at low temperatures thanks to the large overla ...

On the physics of polariton interactions

Naotomo Takemura

An exciton-polariton is a quasi-particle that emerges from the strong coupling between an exciton and a photon. Recently, the studies of the exciton-polariton have been receiving a great deal of attention in terms of both fundamental physics and potential ...

Coherent and incoherent aspects of polariton dynamics in semiconductor microcavities

Benoît Marie Joseph Deveaud, Daniel Oberli, Marcia Portella Oberli, Mitchell David Anderson, Naotomo Takemura, Morteza Navadeh Toupchi, Souvik Biswas

The interaction between coherent polaritons and incoherent excitons plays an important role in polariton physics. Using resonant pump-probe spectroscopy with selective excitation of single polariton branches, we investigate the different dephasing mechanis ...

Proposal for an Optomechanical Bell Test

Christophe Marcel Georges Galland

Photons of a laser beam driving the upper motional sideband of an optomechanical cavity can decay into photon-phonon pairs by means of an optomechanical parametric process. The phononic state can subsequently be mapped to a photonic state by exciting the l ...

Noise-Induced Phenomena in Collective Spinor Polariton Excitations

Hadis Abbaspour

Polaritons are quasiparticles resulting from the strong coupling between photons and excitons embedded in a semiconductor microcavity. The exciton component of polaritons provides strong nonlinear interactions, while their photonic counterpart facilitates ...

Simultaneous observation of the quantization and the interference pattern of a plasmonic near-field

Fabrizio Carbone, Brett Eugene Barwick, Luca Piazza, Yoshie Murooka, Tom Theodorus Antonius Lummen

Surface plasmon polaritons can confine electromagnetic fields in subwavelength spaces and are of interest for photonics, optical data storage devices and biosensing applications. In analogy to photons, they exhibit wave-particle duality, whose different as ...
