Mid-Infrared Thermal Radiation Harvesting using Uncooled Narrow Bandgap GeSn Thermophotovoltaic cell
Gérard Daligou, Mahmoud R. M. Atalla, Cédric Lemieux-Leduc +4
Thermophotovoltaic (TPV) cells are increasingly attractive for applications in industrial waste heat harvesting, aerospace energy management, and compact power generation. Deployin…
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…
Design of an ultra-compact, energy-efficient non-volatile photonic switch based on phase change materials
Khoi Phuong Dao, Juejun Hu, Richard Soref
The on-chip photonic switch is a critical building block for photonic integrated circuits (PICs) and the integration of phase change materials (PCMs) enables non-volatile switch de…
Room-temperature photonic quantum computing in integrated silicon photonics with germanium-silicon single-photon avalanche diodes
Neil Na, Chou-Yun Hsu, Erik Chen +1
Most, if not all, photonic quantum computing (PQC) relies upon superconducting nanowire single-photon detectors (SNSPDs) based on niobium (Nb) operated at a temperature < 4 K. This…
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…

An Integrated Optical Circuit Architecture for Inverse-Designed Silicon Photonic Components
Richard Soref, Dusan Gostimirovic
In this work, we demonstrate a compact toolkit of inverse-designed topologically optimized silicon-photonic devices that are arranged in a plug-and-play fashion to realize many dif…
High-performance Pockels-effect modulation and switching in silicon-based GaP/Si, AlP/Si, ZnS/Si, AlN/3C-SiC, GaAs/Ge, ZnSe/GaAs, and ZnSe/Ge superlattice-on-insulator integrated circuits
Francesco De Leonardis, Richard Soref
We propose new Si-based waveguided Superlattice on Insulator (SLOI) platforms for high-performance electro-optical (EO) 2 x 2 and N x M switching and 1 x 1 modulation; including br…
