Wide bandwidth and high coupling efficiency Si3N4-on-SOI dual-level grating coupler.
Optics Express, 2014 We propose and experimentally demonstrate fiber-to-chip grating couplers with aligned silicon nitride (Si(3)N(4)) and silicon (Si) grating teeth for wide bandwidths and high coupling efficiencies without the use of bottom reflectors.

Fermionic and Majorana Bound States in Hybrid Nanowires with Non-Uniform Spin-Orbit Interaction
, 2014 We study intragap bound states in the topological phase of a Rashba nanowire in the presence of a magnetic field and with non-uniform spin orbit interaction (SOI) and proximity-induced superconductivity gap.

Aporia, 2021 Ce texte propose une réflexion critique à partir de différents travaux autant théoriques qu’empiriques sur la signification du « prendre soin de soi » et plus particulièrement de ceux de Michel Foucault sur la généalogie du souci de soi et des techniques

Energy levels of a parabolically confined quantum dot in the presence of spin-orbit interaction
, 2004 We present a theoretical study of the energy levels in a parabolically confined quantum dot in the presence of the Rashba spin-orbit interaction (SOI). The features of some low-lying states in various strengths of the SOI are examined at finite magnetic ...

Collapse of a tropical forest bird assemblage surrounding a hydroelectric reservoir
Global Ecology and Conservation, 2018 Hydroelectricity is the world's largest source of ‘renewable’ energy, and deployment will expand considerably in the coming decade, with Asian countries installing the bulk of new generating capacity.

Performance of ultra-thin SOI-based resonators for sensing applications.
Optics Express, 2014 This work presents simulation and experimental results of ultra-thin optical ring resonators, having larger Evanescent Field (EF) penetration depths, and therefore larger sensitivities, as compared to conventional Silicon-on-Insulator (SOI)-based ...

, 2011 Persistent, oscillatory charge and spin currents are shown to be driven by a two-component terahertz laser pulse in a one-dimensional mesoscopic ring with Rashba-Dresselhaus spin orbit interactions (SOI) linear in the electron momentum.

Ge-on-Si and Ge-on-SOI thermo-optic phase shifters for the mid-infrared.
Optics Express, 2014 Germanium-on-silicon thermo-optic phase shifters are demonstrated in the 5 μm wavelength range. Basic phase shifters require 700 mW of power for a 2π phase shift.

Controlling short-channel effects in deep-submicron SOI MOSFETs for improved reliability: a review [PDF]
IEEE transactions on device and materials reliability, 2004 This paper examines the performance degradation of a MOS device fabricated on silicon-on-insulator (SOI) due to the undesirable short-channel effects (SCE) as the channel length is scaled to meet the increasing demand for high-speed high-performing ULSI ...
