Focusing of in-plane hyperbolic polaritons in van der Waals crystals with tailored infrared nanoantennas
Javier Martín-Sánchez, Jiahua Duan, Javier Taboada-Gutiérrez +9
Phonon polaritons (PhPs),light coupled to lattice vibrations,with in-plane hyperbolic dispersion exhibit ray-like propagation with large wavevectors and enhanced density of optical…
Planar nano-optics in anisotropic media: anomalous refraction and diffraction-free lensing of highly confined polaritons
J. Duan, G. Álvarez-Pérez, A. I. F. Tresguerres-Mata +13
As one of the most fundamental optical phenomena, refraction between isotropic media is characterized by light bending towards the normal to the boundary when passing from a low- t…
Experimental demonstration of the suppression of optical phonon splitting in 2D materials by Raman spectroscopy
Marta De Luca, Xavier Cartoixà, David I. Indolese +7
Raman spectroscopy is one of the most extended experimental techniques to investigate thin-layered 2D materials. For a complete understanding and modeling of the Raman spectrum of…
Opto-Mechanical Tuning of the Polarization Properties of Micropillar Cavity Systems with embedded Quantum Dots
Stefan Gerhardt, Magdalena Moczała-Dusanowska, Łukasz Dusanowski +7
Strain tuning emerged as an appealing tool to tune fundamental optical properties of solid state quantum emitters. In particular, the wavelength and fine structure of quantum dot s…
New insights in the lattice dynamics of monolayers, bilayers, and trilayers of WSe2 and unambiguous determination of few-layer-flakes' thickness
Marta De Luca, Xavier Cartoixà, Javier Martín-Sánchez +4
Among the most common few-layers transition metal dichalcogenides (TMDs), WSe2 is the most challenging material from the lattice dynamics point of view. Indeed, for a long time the…
A frequency-tunable nanomembrane mechanical oscillator with embedded quantum dots
Xueyong Yuan, Michael Schwendtner, Rinaldo Trotta +10
Hybrid systems consisting of a quantum emitter coupled to a mechanical oscillator are receiving increasing attention for fundamental science and potential applications in quantum t…
Inversion of the exciton built-in dipole moment in In(Ga)As quantum dots via nonlinear piezoelectric effect
Johannes Aberl, Petr Klenovský, Johannes S. Wildmann +6
We show that anisotropic biaxial stress can be used to tune the built-in dipole moment of excitons confined in In(Ga)As quantum dots up to complete erasure of its magnitude and inv…
Reversible Control of In-plane Elastic Stress Tensor in Nanomembranes
Javier Martín-Sánchez, Rinaldo Trotta, Giovanni Piredda +10
Strain engineering allows the physical properties of materials and devices to be widely tailored, as paradigmatically demonstrated by strained transistors and semiconductor lasers…
Atomic Clouds as Spectrally-Selective and Tunable Delay Lines for Single Photons from Quantum Dots
Johannes S. Wildmann, Rinaldo Trotta, Javier Martín-Sánchez +3
We demonstrate a compact, spectrally-selective, and tunable delay line for single photons emitted by quantum dots. This is achieved by fine-tuning the wavelength of the optical tra…
