Predictive wavelength tailoring of uniform GaSb-based quantum dots for emission at 1.55 um
Markus Peil, Maja Wasiluk, Ziemowit Olinkiewicz +11
A detailed study of emission wavelength tailoring of GaSb-based QDs formed by InGaSb-filling of droplet-etched nanoholes in AlGaSb is presented. The study shows that the emission w…
Temperature Dependence of the Refractive Index for AlAsGaSb
Helena Janowska, Wojciech Charaszkiewicz, Maja Wasiluk +6
Accurate design and optimization of photonic multilayer structures like distributed Bragg reflectors (DBRs) require precise knowledge of material optical constants, particularly th…
Nonlinear Optical Microscopy of Semiconductor Metal-Nanocavities
Riya Varghese, Shambhavee Annurakshita, Yaraslau Tamashevich +13
We use second and third harmonic generation microscopy to investigate the nonlinear optical response of GaAs nanocavities embedded in a gold film and compare them to bare GaAs nano…
Purcell-enhanced single-photon emission from InAs/GaAs quantum dots coupled to broadband cylindrical nanocavities
Abhiroop Chellu, Subhajit Bej, Hanna Wahl +16
On-chip emitters that can generate single and entangled photons are essential building blocks for developing photonic quantum information processing technologies in a scalable fash…
Telecom wavelength single-photon emission from quasi-resonantly excited InGaSb/AlGaSb quantum dots
Teemu Hakkarainen, Joonas Hilska, Arttu Hietalahti +10
Deterministic light sources capable of generating quantum states on-demand at wavelengths compatible with fiber optics and atmospheric transmission windows are essential for practi…
Electronic structure of GaSb/AlGaSb quantum dots formed by filling droplet-etched nanoholes
Lucie Leguay, Abhiroop Chellu, Joonas Hilska +4
Epitaxially-grown semiconductor quantum dots (QDs) provide an attractive platform for the development of deterministic sources of high-quality quantum states of light. Such non-cla…
Strain-free GaSb quantum dots as single-photon sources in the telecom S-band
Johannes Michl, Giora Peniakov, Andreas Pfenning +7
Creating single photons in the telecommunication wavelength range from semiconductor quantum dots (QDs) and interfacing them with spins of electrons or holes has been of high inter…
Highly uniform GaSb quantum dots with indirect-direct bandgap crossover at telecom range
Abhiroop Chellu, Joonas Hilska, Jussi-Pekka Penttinen +1
We demonstrate a new quantum-confined semiconductor material based on GaSb quantum dots (QDs) embedded in single-crystalline AlGaSb matrix by filling droplet-etched nanoholes. The…
Nanohole etching in AlGaSb with Ga droplets
Joonas Hilska, Abhiroop Chellu, Teemu Hakkarainen
We demonstrate nanohole formation in AlGaSb by Ga droplet etching within a temperature range from 270°C to 500°C, allowing a wide range of tunability of the nanohole density. By le…
