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…
An intuitive scheme for the restoration of entanglement for polarization-entangled photons emitted from quantum dots with non-vanishing fine structure splitting
Simone Varo, Gediminas Juska, Emanuele Pelucchi
Generation of polarization-entangled photons from quantum dots via the biexciton-exciton recombination cascade is complicated by the presence of an energy spitting between the inte…
The importance of overcoming MOVPE surface evolution instabilities for >1.3 m metamorphic lasers on GaAs
Enrica E. Mura, Agnieszka M. Gocalinska, Megan O'Brien +7
We investigated and demonstrated a 1.3 m-band laser grown by metalorganic vapour phase epitaxy (MOVPE) on a specially engineered metamorphic parabolic graded InGaAs…
