Dynamics of coupled spins in quantum dots with strong spin-orbit interaction

A. Pfund, I. Shorubalko, K. Ensslin, R. Leturcq

We investigated the time dependence of two-electron spin states in a double quantum dot fabricated in an InAs nanowire. In this system, spin-orbit interaction has substantial influence on the spin states of confined electrons. Pumping single electrons through a Pauli spin-blockade configuration…

Micro-systèmes et contrôle d'écoulements

Alain Merlen, Philippe Pernod, Abdelkrim Talbi, Romain Viard, Leticia Gimeno

Les micro-systèmes magnéto-mécaniques présentent des possibilités intéressantes en matière de contrôle d'écoulements. Ils permettent de remplir les cahiers des charges des constructeurs aéronautiques ou automobiles. Ils sont également plus facilement intégrables sur les prototypes que les MEMS…

Design considerations for 1.3 µm GaNAsSb-GaAs high speed and high quantum efficiency waveguide photodetectors

Z. Xu, Soon Fatt Yoon, Wan Khai Loke, Chunyong Ngo, Kianhuan Tan, Satrio Wicaksono, N. Saadsaoud, Didier Decoster, Malek Zegaoui, Jean Chazelas

The electrical and optical characteristics of a 1.3 μm GaNAsSb-GaAs p-i-n waveguide photodetector (WGPD), consisting of GaAs inner and AlxGa1-xAs outer cladding layers, were simulated using a lumped-element model and finite difference beam propagation method (BPM). The effect of multiple cladding…

Design, optimization and fabrication of an optical mode filter for integrated optics

V. Magnin, Malek Zegaoui, Joseph Harari, M. François, Didier Decoster

We present the design, optimization, fabrication and characterization of an optical mode filter, which attenuates the snaking behavior of light caused by a lateral misalignment of the input optical fiber relative to an optical circuit. The mode filter is realized as a bottleneck section inserted in…

Assessment of carrier-multiplication efficiency in bulk PbSe and PbS

Joep J. H. Pijpers, Ronald Ulbricht, Klaas-Jan Tielrooij, A. Osherov, Y. Golan, Christophe Delerue, Guy Allan, Mischa Bonn

One of the important factors limiting solar-cell efficiency is that incident photons generate one electron–hole pair, irrespective of the photon energy. Any excess photon energy is lost as heat. The possible generation of multiple charge carriers per photon (carrier multiplication) is therefore of…
