Generation of C-band entangled photon pairs by biexciton-exciton cascade from symmetric InAs/InP quantum dots
Anna Musiał, Maja Wasiluk, Katarzyna Roszak +6
Hereby, we study the generation of pairs of polarization-entangled photons at telecom C-band by biexciton-exciton cascade from non-resonantly excited epitaxial InAs/InP quantum dot…
High-reflectivity homoepitaxial distributed Bragg reflectors for photonic applications
Helena Janowska, Anna Musiał, Grzegorz Sęk
Distributed Bragg reflectors (DBRs) are one of the basic photonic structures used to define microcavities for fundamental light-matter coupling studies, as well as to optimize perf…
Optical characteristics of cavity structures with Al0.2Ga0.8As/Al0.9Ga0.1As distributed Bragg reflectors and In0.37Ga0.63As quantum dots as the active region
Bartosz Kamiński, Agata Zielińska, Anna Musiał +5
We characterized optically In0.37Ga0.63As/GaAs quantum dots and Al0.2Ga0.8As/Al0.9Ga0.1As distributed Bragg reflector based cavities. The main mechanisms of quantum dots photolumin…
Optical and electronic properties of symmetric InAs/InGaAlAs/InP quantum dots formed by a ripening process in molecular beam epitaxy: a promising system for broad-range single-photon telecom emitters
Paweł Holewa, Michał Gawełczyk, Aleksander Maryński +5
We present a detailed experimental optical study supported by theoretical modeling of InAs quantum dots (QDs) embedded in an InAlGaAs barrier lattice-matched to InP(001) grown with…
Observation of gain-pinned dissipative solitons in a microcavity laser
Maciej Pieczarka, Dario Poletti, Christian Schneider +4
We demonstrate an experimental approach to create dissipative solitons in a microcavity laser. In particular, we shape the spatial gain profile of a quasi-one-dimensional microcavi…
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…
Exciton spin relaxation in InAs/InGaAlAs/InP(001) quantum dashes emitting near 1.55 μm
M. Syperek, Ł. Dusanowski, M. Gawełczyk +5
Exciton spin and related optical polarization in self-assembled InAs/InGaAlAs/InP(001) quantum dashes emitting at 1.55 μm are investigated by means of po…
Modelling the enhancement of spectrally broadband extraction efficiency of emission from single InAs/InP quantum dots at telecommunication wavelengths
Paweł Mrowiński, Grzegorz Sęk
Hereby, we present results of finite-difference time-domain simulations of technologically undemanding photonic structures offering a significant improvement in the spectrally broa…
