Polarization-sensitive GeSn Mid-Infrared Membrane Photodetectors with Integrated Plasmonic Metasurface
Ziqiang Cai, Cédric Lemieux-Leduc, Mahmoud R. M. Atalla +4
Germanium-Tin (GeSn) semiconductors are promising for mid-infrared optoelectronics owing to their silicon compatibility, tunable bandgap, and potential for room-temperature operati…
Waveguide-Coupled Mid-Infrared GeSn Membrane Photodetectors on Silicon-on-Insulator
Cédric Lemieux-Leduc, Mahmoud R. M. Atalla, Simone Assali +5
Silicon photonics has thrived in telecommunications over recent decades, and its extension to the mid-infrared range has the potential to unlock valuable opportunities for sensing,…
Current Crowding in a High-Efficiency Black Phosphorus Light-Emitting Diode Using a Reflective Back Contact
Julien Brodeur, Éloïse Rahier, Mathieu Chartray-Pronovost +3
We demonstrate a high-performance mid-infrared (MIR) light-emitting diode (LED) based on a black phosphorus (b-P)/n-MoS heterojunction. A gold back contact combined with a rhen…
Remote Electric Powering by Germanium Photovoltaic Conversion of an Erbium-Fiber Laser Beam
Richard Soref, Francesco De Leonardis, Oussama Moutanabbir +1
The commercially available 4000-Watt continuous-wave Erbium-doped-fiber laser, emitting at the 1567-nanometer wavelength where the atmosphere has high transmission, provides an opp…
Directed High-Energy Infrared Laser Beams for Photovoltaic Generation of Electric Power at Remote Locations
Richard Soref, Francesco De Leonardis, Gerard Daligou +1
Transferring energy without transferring mass is a powerful paradigm to address the challenges faced when the access to, or the deployment of, the infrastructure for energy convers…
Transfer-printed multiple GeSn membrane mid-infrared photodetectors
Cédric Lemieux-Leduc, Mahmoud R. M. Atalla, Simone Assali +8
Due to their narrow band gap and compatibility with silicon processing, germanium-tin (GeSn) alloys are a versatile platform for scalable integrated mid-infrared photon…
