Distributed Bragg reflector-mediated excitation of InAs/InP quantum dots emitting in the telecom C-band
A. Musiał, M. Wasiluk, M. Gawełczyk +4
We demonstrate that optical excitation of InAs quantum dots (QDs) embedded directly in an InP matrix can be mediated via states in a quaternary compound constituting an InP/InGaAlA…
Excited states of neutral and charged excitons in single strongly asymmetric InP-based nanostructures emitting in the telecom C band
M. Gawełczyk, P. Wyborski, P. Podemski +3
We investigate strongly asymmetric self-assembled nanostructures with one of dimensions reaching hundreds of nanometers. Close to the nanowire-like type of confinement, such object…
InP-based single-photon sources operating at telecom C-band with increased extraction efficiency
A. Musiał, M. Mikulicz, P. Mrowiński +7
In this work we demonstrate a triggered single-photon source operating at the telecom C-band with photon extraction efficiency exceeding any reported values in this range. The non-…
Thermal stability of emission from single InGaAs/GaAs quantum dots at the telecom O-band
Paweł Holewa, Marek Burakowski, Anna Musiał +6
Single-photon sources are key building blocks in most of the emerging secure telecommunication and quantum information processing schemes. Semiconductor quantum dots (QD) have been…
Interplay between emission wavelength and s-p splitting in MOCVD-grown InGaAs/GaAs quantum dots emitting above 1.3 μm
Paweł Podemski, Anna Musiał, Krzysztof Gawarecki +11
The electronic structure of strain-engineered single InGaAs/GaAs quantum dots emitting in the telecommunication O band is probed experimentally by photoluminescence excitation spec…
Excitonic complexes in MOCVD-grown InGaAs/GaAs quantum dots emitting at telecom wavelengths
Paweł Mrowiński, Anna Musiał, Krzysztof Gawarecki +8
Hereby, we present a comprehensive experimental and theoretical study of the electronic structure and optical properties of excitonic complexes in strain-engineered InGaAs/GaAs qua…
Enhanced photon-extraction efficiency from InGaAs/GaAs quantum dots in deterministic photonic structures at 1.3 μm fabricated by in-situ electron-beam lithography
Nicole Srocka, Anna Musiał, Philipp-Immanuel Schneider +8
The main challenge in the development of non-classical light sources remains their brightness that limits the data transmission and processing rates as well as the realization of p…
Monolayer MoSe2: A candidate for room temperature polaritonics
N. Lundt, A. Maryński, E. Cherotchenko +7
Monolayered MoSe2 is a promising new material to investigate advanced light-matter coupling as it hosts stable and robust excitons with comparably narrow optical resonances. In thi…
Ghost Branch Photoluminescence From a Polariton Fluid Under Nonresonant Excitation
Maciej Pieczarka, Marcin Syperek, Łukasz Dusanowski +8
An expanding polariton condensate is investigated under pulsed nonresonant excitation with a small laser pump spot. Far above the condensation threshold we observe a pronounced inc…
Hole subband mixing and polarization of luminescence from quantum dashes: a simple model
Piotr Kaczmarkiewicz, Anna Musiał, Grzegorz Sęk +3
In this paper, we address the problem of luminescence polarization in the case of nanostructures characterized by an in-plane shape asymmetry. We develop a simple semi-qualitative…
