A new kind of solid-state contact for ion-selective electrodes based on solvent polymeric membranes is described. These electrodes show similar electrochemical behaviour to conventional ion-selective membranes in contact with an internal filling solu

We compare quantitatively the transmission properties of various 60/spl deg/ bends carved into a photonic crystal based on a two-dimensional triangular lattice of holes perforating a GaAs-based heterostructure. The bends are inserted into channel wav

In this paper, we present an improved version of microcavity light-emitting diodes, relying on the use of a low-index material, aluminum oxide. Our work addresses in particular the injection scheme required by the insulating nature of this oxide. The

The use of photonic crystals (PCs) for realistic light emitting diodes (LEDs) is discussed, given the constraints of planar semiconductor technology. A viable route for the fabrication of high-efficiency high-brightness electrically injected LEDs is

In this paper, we present a systematic study of the effect of growth parameters on the structural and optical properties of InAs quantum dot (QD) grown under Stranski-Krastanov mode by molecular beam epitaxy. The dot density is significantly reduced

We introduce to the physics of semiconductor microcavities in the strong coupling regime, also known as cavity-polariton. We discuss the optical response, cavity-polariton dispersion curve, inhomogeneous broadening due to disorder effect and homogene

We report on the linear response of cavity-polariton states and elastic scattering effects. We discuss the effects of disorder and phonon scattering on reflectivity and transmission and its consequence on the elastic scattering of light on high quali

A detailed characterization and modeling of long-wavelength (/spl lambda//spl sim/10 /spl mu/m) quantum cascade (QC) lasers based on a photon-assisted tunneling transition are presented. In particular, the influence of the finite lifetime of the lowe

Resonant scattering by cavity polaritons in a semiconductor microcavity is investigated. The bidimensional photonic behavior is well shown by the angular spread of the Rayleigh scattered light on the elastic cone. Moreover, the strong coupling betwee
