Mid-Infrared Optical Spin Injection and Coherent Control
Gabriel Fettu, John E. Sipe, Oussama Moutanabbir
The optical injection of charge and spin currents are investigated in GeSn semiconductors as a function of Sn content. These emerging silicon-compatible materials ena…
Polarization-Tuned Fano Resonances in All-Dielectric Short-Wave Infrared Metasurface
Anis Attiaoui, Gérard Daligou, Simone Assali +3
The short-wave infrared (SWIR) is an underexploited portion of the electromagnetic spectrum in metasurface-based nanophotonics despite its strategic importance in sensing and imagi…
Light-Hole Gate-Defined Spin-Orbit Qubit
Patrick Del Vecchio, Oussama Moutanabbir
The selective confinement of light-holes (LHs) is demonstrated by introducing a low-dimensional system consisting of highly tensile-strained Ge quantum well enabling the design of…
500-period epitaxial Ge/Si0.18Ge0.82 multi-quantum wells on silicon
Simone Assali, Sebastian Koelling, Zeinab Abboud +3
Ge/SiGe multi-quantum well heterostructures are highly sought-after for silicon-integrated optoelectronic devices operating in the broad range of the electromagnetic spectrum cover…
Localized Energy States Induced by Atomic-Level Interfacial Broadening in Heterostructures
Anis Attiaoui, Gabriel Fettu, Samik Mukherjee +2
A theoretical framework incorporating atomic-level interfacial details is derived to include the electronic structure of buried interfaces and describe the behavior of charge carri…
Dark current in monolithic extended-SWIR GeSn PIN photodetectors
Mahmoud R. M. Atalla, Simone Assali, Sebastian Koelling +2
The monolithic integration of extended short-wave infrared (e-SWIR) photodetectors (PDs) on silicon is highly sought-after to implement manufacturable, cost-effective sensing and i…
