A wavelength-self-tunable single-sideband filter is proposed so as to compensate for deleterious chromatic dispersion effets in fiber-radio systems. First we describe...

The integration on silicon of direct band gap materials such as some semiconductors from the III-V group is of a rising interest for tomorrow's optoelectronic devices....

Room temperature continuous-wave (CW) operation is the crucial milestone that promotes a semiconductor laser from an object of research to a device for the world of...

The physicochemical properties of a spherical semiconductor nanocrystal, intermediate between the molecule and the solid depend on its size. Stacked or dispersed,...

This thesis work has focused on the synthesis of (In)GaN-based quantum dot (QD) structures by plasma-assisted molecular-beam epitaxy (PAMBE), deposited in both polar...

This work reports on electronic design, epitaxial growth and characterization of GaN/Al(Ga)N quantum wells which constitute the active region of intersubband (ISB)...

The aim of this work is to model the properties of GaInAsNSb/GaAs compressively strained structures. Indeed, Ga1−xInxAs1−y−zNySbz has been found to be a potentially...

Silicon photonics is a research field in full expansion that works towards the integration of photonics and microelectronic components in a single chip. The creation...

Silicon non linear optics is of considerable interest to the scientific community because of its applications to integrated optoelectronics. In order to observe non...

This work is aimed at the study of GaInP-based photovoltaic cell. The effects of In content, lattice parameter mismatch and thickness of the SiO2 insulating layer on...

The subject of the thesis focused on the development, characterization and use of semiconductor materials, in which the free carriers have a very short lifetime...

International audience

This PhD work was devoted to the study of ultrafast optoelectronic components for processing RF signals up to the THz range, and of related THz devices. First, we used...

In this paper we present the simulation of Metal-Semiconductor-Metal photodetector (MSM-PD) of interdigitated planar structure based on InAlAs/InGaAs adapted for...

In this paper we present the optimization of photoswitches constituted of a coplanar line introducing interdigitated MSM photodetectors in the central strip. The...
