Crosstalk measurement of DOS-like switch using InP narrow deep-etched waveguides

Marie Lesecq, Maxime Beaugeois, Sophie Maricot, Jean-Pierre Vilcot

We report on the performance of an optical switch based on the use of narrow deep-etched InP waveguides. A DOS-like structure has been designed and fabricated. First characterization results are reported. They show an optical crosstalk value close to -20dB.

Hysteretic magnetotransport in p-type AlxGa1-xAs heterostructures with In/Zn/Au ohmic contacts

B. Grbic, R. Leturcq, T. Ihn, K. Ensslin, G. Blatter, D. Reuter, A.D. Wieck

The two-terminal magneto-conductance of a hole gas in C-doped AlGaAs/GaAs heterostructures with ohmic contacts consisting of alloyed In/Zn/Au displays a pronounced hysteresis of the conductance around zero magnetic field. The hysteresis disappears above magnetic fields of around 0.5 T and…

Detecting single-electron tunneling involving virtual processes in real time

S. Gustavsson, M. Studer, R. Leturcq, T. Ihn, K. Ensslin, D.C. Driscoll, A.C. Gossard

We use time-resolved charge detection techniques to probe virtual tunneling processes in a double quantum dot. The process involves an energetically forbidden state separated by an energy δ from the Fermi energy in the leads. The non-zero tunneling probability can be interpreted as cotunneling,…

Investigation on the emission wavelength of GaInNAs/GaAs strained compressive quantum wells on GaAs substrates

Abdelkader Aissat, Said Nacer, Messaoud Bensebti, Jean-Pierre Vilcot

In this paper, we study the effect of the incorporation of nitrogen in strained GaInAs quantum well structures. We evaluate the influence of nitrogen on the conduction band energy by using the band anticrossing model. The incorporation of nitrogen appears to decrease the bandgap energy and increase…

Monte Carlo modeling of carrier-carrier scattering in semiconductors with nonparabolic bands

Olivier Bonno, Jean-Luc Thobel

An efficient algorithm to account for nonparabolicity in carrier-carrier scattering in an ensemble Monte Carlo simulator is proposed. The major difficulty of modeling intercarrier scattering in semiconductors with nonparabolic bands arises from the two particle momentum and energy conservation laws…
