Purcell-enhanced single-photon generation from CsPbBr quantum dots in in-situ selected Laguerre-Gaussian modes
Virginia Oddi, Darius Urbonas, Etsuki Kobiyama +9
Single photons in Laguerre-Gaussian (LG) beams, which carry orbital angular momentum (OAM), could enable more robust and efficient photonic quantum communication and information pr…
Deterministic Integration of CsPbBr3 Quantum Dots with Plasmonic Ring Microcavities
Pengji Li, Chenxi Ma, Jingzhong Yang +8
Perovskite quantum dots hold great promise for quantum information processing as wavelength-tunable single photon sources operable over a broad temperature range. However, their de…
Transition between cooperative emission regimes in giant perovskite nanocrystals
Etsuki Kobiyama, Gabriele Rainò, Yuliia Berezovska +6
Interactions between emitters within an ensemble can give rise to cooperative processes that significantly alter the properties of the emitted light. One such process is superfluor…
Room-temperature cavity exciton-polariton condensation in perovskite quantum dots
Ioannis Georgakilas, David Tiede, Darius Urbonas +13
The exploitation of the strong light-matter coupling regime and exciton-polariton condensates has emerged as a compelling approach to introduce strong interactions and nonlineariti…
Perovskite nanocrystal self-assemblies in 3D hollow templates
Etsuki Kobiyama, Darius Urbonas, Maryna I. Bodnarchuk +7
Highly ordered nanocrystal (NC) assemblies, namely superlattices (SLs), have been investigated as novel building blocks of optical and optoelectronic devices due to their unique pr…
Phonon-driven wavefunction localization promotes room-temperature, pure single-photon emission in large organic-inorganic lead-halide quantum dots
Leon G. Feld, Simon C. Boehme, Sebastian Sabisch +13
In lead halide perovskites (APbX3), the effect of the A-site cation on optical and electronic properties has initially been thought to be marginal. Yet, evidence of beneficial effe…
Circularly Polarized Luminescence Without External Magnetic Fields from Individual CsPbBr3 Perovskite Quantum Dots
Virginia Oddi, Chenglian Zhu, Michael A. Becker +8
Lead halide perovskite quantum dots (QDs), the latest generation of colloidal QD family, exhibit outstanding optical properties which are now exploited as both classical and quantu…
Electric-field-resolved detection of localized surface plasmons at petahertz-scale frequencies
Dmitry A. Zimin, Ihor Cherniukh, Simon C. Böhme +3
We present a novel electric-field-resolved approach for probing ultrafast dynamics of localized surface plasmons in metallic nanoparticles. The electric field of the broadband carr…
Phonon-Mediated Attractive Interactions between Excitons in Lead-Halide-Perovskites
Nuri Yazdani, Maryna I. Bodnarchuk, Federica Bertolotti +20
Understanding the origin of electron-phonon coupling in lead-halide perovskites (LHP) is key to interpreting and leveraging their optical and electronic properties. Here we perform…
On-Chip Integrated Quantum-Dot Silicon-Nitride Microdisk Lasers
Weiqiang Xie, Thilo Stöferle, Gabriele Rainò +8
Hybrid SiN-QD microlasers coupled to a passive SiN output waveguide with 7μm diameter and record low threshold density of 27 μJ cm-2 are demonstrated. A new design and unique proce…
Long Exciton Dephasing Time and Coherent Phonon Coupling in CsPbBrCl Perovskite Nanocrystals
Michael A. Becker, Lorenzo Scarpelli, Georgian Nedelcu +7
Fully-inorganic cesium lead halide perovskite nanocrystals (NCs) have shown to exhibit outstanding optical properties such as wide spectral tunability, high quantum yield, high osc…
Superfluorescence from Lead Halide Perovskite Quantum Dot Superlattices
Gabriele Rainò, Michael A. Becker, Maryna I. Bodnarchuk +3
An ensemble of emitters can behave significantly different from its individual constituents when interacting coherently via a common light field. After excitation, collective coupl…
Bright triplet excitons in lead halide perovskites
Michael A. Becker, Roman Vaxenburg, Georgian Nedelcu +13
Nanostructured semiconductors emit light from electronic states known as excitons[1]. According to Hund's rules[2], the lowest energy exciton in organic materials should be a poorl…
