L-band single-photon generation from a cavity-coupled silicon C-center
Carolina Crosta, Kyu-Young Kim, Purbita Purkayastha +7
Monolithic integration of single-photon sources into silicon photonics offers a compelling solution for realizing scalable quantum telecommunication architectures. Among the candid…
Bright Telecom Spin-Photon Interface in Silicon Photonics
Carolina Crosta, Amirehsan Alizadehherfati, Purbita Purkayastha +5
Silicon is an attractive host for scalable quantum photonics, but the absence of bright telecom-band emitters with optically addressable spin states has limited its use for spin-ph…
Formation of C-centers in Si-based systems by light ion irradiation
Carolina Crosta, Riccardo Nardin, Patrick Daoust +8
Atomic-scale crystal defects in Si are quantum-light sources offering tantalizing integration with existing photonic technologies. Yet, the controlled creation of near-infrared col…
Optical spin pumping in silicon
Stefano Achilli, Damiano Marian, Mario Lodari +5
The generation of an out-of-equilibrium population of spin-polarized carriers is a keystone process for quantum technologies and spintronics alike. It can be achieved through the s…
Giant spin-to-charge conversion in germanium tin epilayers
S. Oyarzún, C. Gonzalez-Fuentes, Erick Burgos +4
We report a study of the spin-to-charge current conversion in compressively strained Ge1-xSnx alloy epilayers as a function of the Sn concentration by means of the inverse spin Hal…
Optical control of the spin-Hall effect in a two-dimensional hole gas
Simone Rossi, Valentina Caprotti, Andrea Filippi +5
Relativistic effects influence the motion of charged particles in solids by intertwining spin and momentum. The resulting phenomena exhibit rich and intriguing properties that can…
Photoluminescence study of interband transitions in few-layer, pseudomorphic, and strain-unbalanced Ge/GeSi multiple quantum wells
M. Montanari, M. Virgilio, C. L. Manganelli +11
In this paper we investigate the structural and optical properties of few strain-unbalanced multiple Ge/GeSi quantum wells pseudomorphically grown on GeSi reverse-graded substrates…
Spin-dependent direct gap emission in tensile-strained Ge films on Si substrates
E. Vitiello, M. Virgilio, A. Giorgioni +7
The circular polarization of direct gap emission of Ge is studied in optically-excited tensile-strained Ge-on-Si heterostructures as a function of doping and temperature. Owing to…
