Exciton–polaritons in van der Waals heterostructures embedded in tunable microcavities
The results pave the way for room-temperature polaritonic devices based on multiple-quantum-well van der Waals heterostructures, where polariton condensation and electrical polariton injection through the incorporation of graphene contacts may be realized.
Strong coupling phenomena in quantum microcavity structures
The physics of strong coupling phenomena in semiconductor quantum microcavities is reviewed. This is a relatively new field with most important developments having occurred in the last 5 years. We
Inverted electron-hole alignment in InAs-GaAs self-assembled quantum dots.
It is demonstrated that the excited state transitions arise from lateral quantization and that tuning through the inhomogeneous distribution of dot energies can be achieved by variation of electric field.
Collective fluid dynamics of a polariton condensate in a semiconductor microcavity
Using a coherent excitation triggered by a short optical pulse, a macroscopically degenerate state of polaritons are created that can be made to collide with a variety of defects present in the microcavity and opens the way to the investigation of new phenomenology of out-of-equilibrium condensates.
Strong exciton–photon coupling in an organic semiconductor microcavity
The modification and control of exciton–photon interactions in semiconductors is of both fundamental and practical interest, being of direct relevance to the design of improved light-emitting diodes,
Improved performance of 1.3μm multilayer InAs quantum-dot lasers using a high-growth-temperature GaAs spacer layer
The use of a high-growth-temperature GaAs spacer layer is demonstrated to significantly improve the performance of 1.3μm multilayer self-assembled InAs∕InGaAs dot-in-a-well lasers. The
Damping of exciton Rabi rotations by acoustic phonons in optically excited InGaAs/GaAs quantum dots.
We report experimental evidence identifying acoustic phonons as the principal source of the excitation-induced-dephasing (EID) responsible for the intensity damping of quantum dot excitonic Rabi
Exciton-light coupling in single and coupled semiconductor microcavities: Polariton dispersion and polarization splitting
A comprehensive theoretical and experimental study of linear exciton-light coupling in single and coupled semiconductor microcavities is presented: emphasis is given to angular dispersion and
Cavity-polariton dispersion and polarization splitting in single and coupled semiconductor microcavities
Recent theoretical and experimental work on linear exciton-light coupling in single and coupled semiconductor microcavities is reviewed: emphasis is given to angular dispersion and polarization
Observation of bright polariton solitons in a semiconductor microcavity
Microcavity polaritons are composite half-light half-matter quasiparticles, which have recently been demonstrated to exhibit rich physical properties, such as nonequilibrium condensation, parametric
