Optimization of InAs/InAlGaAs/InP quantum dots for O-band laser applications
Anna Penkała, Paweł Podemski, Vinayakrishna Joshi +3
The O-band telecommunication spectral range combines minimal chromatic dispersion with low transmission loss, making it highly suitable for optical communications. Semiconductor te…
Effects of dislocation filtering layers on optical properties of third telecom window emitting InAs/InGaAlAs quantum dots grown on silicon substrates
Wojciech Rudno-Rudziński, Michał Gawełczyk, Paweł Podemski +6
Integrating light emitters based on III-V materials with silicon-based electronics is crucial for further increase in data transfer rates in communication systems since the indirec…
Impact of MBE-grown (In,Ga)As/GaAs metamorphic buffers on excitonic and optical properties of single quantum dots with single-photon emission tuned to the telecom range
Paweł Wyborski, Michał Gawełczyk, Paweł Podemski +6
Tuning GaAs-based quantum emitters to telecom wavelengths makes it possible to use the existing mature technology for applications in, e.g., long-haul ultra-secure communication in…
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…
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…
Single dot photoluminescence excitation spectroscopy in the telecommunication spectral range
Paweł Podemski, Aleksander Maryński, Paweł Wyborski +3
Single dot photoluminescence excitation spectroscopy provides an insight into energy structure of individual quantum dots, energy transfer processes within and between the dots and…
Carrier trapping and luminescence polarization in quantum dashes
A. Musiał, P. Kaczmarkiewicz, G. Sęk +6
We study experimentally and theoretically polarization-dependent luminescence from an ensemble of quantum-dot-like nanostructures with a very large in-plane shape anisotropy (quant…
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…
