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…
