Site-controlled quantum dot arrays edge-coupled to integrated silicon nitride waveguides and devices
John O'Hara, Nicola Maraviglia, Mack Johnson +7
The scalability of quantum photonic integrated circuits opens the path towards large-scale quantum computing and communication. To date, this scalability has been limited by the st…
Trion quantum coherence in site-controlled pyramidal InGaAs quantum dots
R. A. Barcan, I. Samaras, K. Barr +3
Deterministically positioned pyramidal InGaAs quantum dots (QDs) exhibit exceptional quantum properties, making them highly promising candidates for scalable on-chip quantum inform…
Self-aligned pillar arrays embedding site-controlled single quantum dots for enhanced non-classical light emission
Gediminas Juska, Simone Varo, Nicola Maraviglia +8
This work presents a foundational approach for fabricating arrays of self-aligned micro- and nanopillar structures incorporating individual site-controlled quantum dots (QDs) for e…
Optical pumping and initialization of a hole spin in site-controlled InGaAs pyramidal quantum dots
R. A. Barcan, I. Samaras, K. Barr +3
We investigate site-controlled InGaAs quantum dots in (111)B GaAs pyramidal recesses as spin qubits. Combining scanning confocal cryomicroscopy, magneto-photolumi…
On the multifaceted journey for the invention of epitaxial quantum dots
Emanuele Pelucchi
Epitaxial semiconductor quantum dots have been, in the last 40 years or so, at the center of the research effort of a large community. The focus being on semiconductor physics and…
Statistical study of stacked/coupled site-controlled pyramidal quantum dots and their excitonic properties
S. T. Moroni, T. H. Chung, G. Juska +2
We report on stacked multiple quantum dots (QDs) formed inside inverted pyramidal recesses, which allow for the precise positioning of the QDs themselves. Specifically we fabricate…
Excitonic lasing of strain-free InP(As) quantum dots in AlInAs microdisk
D. V. Lebedev, M. M. Kulagina, S. I. Troshkov +13
Formation, emission and lasing properties of strain-free InP(As)/AlInAs quantum dots (QDs) embedded in AlInAs microdisk (MD) cavity were investigated using transmission electron mi…
Semiconductor nanostructures engineering: Pyramidal quantum dots
E. Pelucchi, V. Dimastrodonato, L. O. Mereni +2
Pyramidal quantum dots (QDs) grown in inverted recesses have demonstrated over the years an extraordinary uniformity, high spectral purity and strong design versatility. We discuss…
