AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Optical low coherence reflectometry (OLCR) is non-destructive interferometric technique that allows measuring amplitude and phase of the light reflected from the device under test. OLCR is a powerful tool for the characterization of the various optical dev ...

We report on the current properties of Al1-x InxN (x approximate to 0.18) layers lattice- matched ( LM) to GaN and their specific use to realize nearly strain- free structures for photonic and electronic applications. Following a literature survey of the g ...
This work presents the development of an original concept of a side pumped diode pumped crystal laser for the generation of a high power near diffraction limited beam for material processing applications such as cutting, marking and drilling. An approach b ...
Among all scattering processes, spontaneous Brillouin scattering originates from the interaction between light and thermal acoustic waves propagating in the medium. The interference resulting from the incident light and its spontaneously backscattered frac ...
We study the optical properties of strongly photo-excited GaAs/AlxGa1-xAs Quantum Wells in the one-dimensional optical amplifier geometry. One part of our work deals with gain measurements using the "variable stripe length method". We are proposing two new ...
Strained In0.35Ga0.65As/GaAs quantum wells of various thicknesses (6-16 monolayers) obtained by molecular beam epitaxy at 400 degrees C were studied by optical pumping techniques at 4 K. Improved quantum well optical properties, due to significant increase ...
Spin orientation by optical pumping experiments were undertaken on three strained In0.2Ga0.8As/GaAs QW's with different thicknesses. The results concerning the circular degree of polarization dependence on the exciting energy are very different from well t ...
A new far-infrared polarimeter diagnostic for the tokamak a configuration variable (TCV) is under construction at CRPP. It uses two FIR lasers at 432.5 mu m, optically pumped by a 120 W continuous wave CO2 laser. The two FIR cavities will be detuned such t ...
We present a digital holographic microscope that permits one to image polarization state. This technique results from the coupling of digital holographic microscopy and polarization digital holography. The interference between two orthogonally polarized re ...
