Multi-orbital tight binding model for cavity-polariton lattices
(IOP Publishing, 2020-05)
In this work we present a tight-binding model that allows to describe with a minimal amount of parameters the band structure of exciton-polariton lattices. This model based on s and p non-orthogonal photonic orbitals ...
Metal-insulator-metal surface plasmon polariton waveguide filters with cascaded transverse cavities
(Institute of Electrical and Electronics Engineers - IEEEPiscataway, 2011-03)
In this work we propose a new approach for the design of resonant structures aiming at wavelength filtering applications. The structure consists of a subwavelength metal-insulator-metal (MIM) waveguide presenting cascaded ...
Spin-spin indirect interaction at low-energy excitation in zero-dimensional cavities
(IOP Publishing, 2011-05)
We solve the low-energy part of the spectrum of a model that describes a circularly polarized cavity mode strongly coupled to two exciton modes, each of which is coupled to a localized spin of arbitrary magnitude. In the ...
Polariton Resonances for Ultrastrong Coupling Cavity Optomechanics in GaAs/AlAs Multiple Quantum Wells
(American Physical Society, 2015-12)
Polariton-mediated light-sound interaction is investigated through resonant Brillouin scattering experiments in GaAs/AlAs multiple-quantum wells. Photoelastic coupling enhancement at exciton-polariton resonance reaches 105 ...
Dynamical properties of polaritons in semiconductor microcavities
(UniandesMaestría en Ciencias - FísicaFacultad de CienciasDepartamento de Física, 2005)
The main aim of the present thesis work is to study the fundamental features of the different relaxation process for polaritons, when the semiconductor micro-cavity is excited by a non-resonantlaser pump. Our numerical ...
Sub-diffractional cavity modes of terahertz hyperbolic phonon polaritons in tin oxide

Excited states of exciton-polariton condensates in 2D and 1D harmonic traps
(American Physical Society, 2014-05)
We present a theoretical description of Bogolyubov-type excitations of exciton-polariton Bose-Einstein condensates (BECs) in semiconductor microcavities. For a typical two-dimensional (2D) BEC we focus on two limiting ...
Non-linear excitation of polariton cavity modes in ZnO single nanocombs
(Optical Society Of America, 2014-02)
Tunable second harmonic (SH) polaritons have been efficiently generated in ZnO nanocombs, when the material is excited close to half of the band-gap. The nonlinear signal couples to the nanocavity modes, and, as a result, ...
Polariton-driven phonon laser
(Nature, 2020-09)
Efficient generation of phonons is an important ingredient for a prospective electrically-driven phonon laser. Hybrid quantum systems combining cavity quantum electrodynamics and optomechanics constitute a novel platform ...
