2-mu m WAVELENGTH RANGE InGa(Al)As/InP-AlGaAs/GaAs WAFER FUSED VCSELs for SPECTROSCOPIC APPLICATIONS

Elyahou Kapon, Alok Rudra, Alexandru Mereuta, Vladimir Iakovlev, Andrei Caliman

We demonstrate 2-mu m wavelength, wafer-fused InGa(Al)As/InP-AlGaAs/GaAs vertical-cavity surface-emitting lasers (VCSELs) emitting single-mode power of 0.5 mW at room-temperature with a threshold current of 4mA and side-mode suppression ratio of over 30 dB ...

Hierarchical Image Registration with an Active Contour-Based Atlas Registration Model

Jean-Philippe Thiran, Valérie Duay, Subrahmanyam Venkata Ravi Mohana Sai Gorthi, Nawal Houhou

This paper proposes to apply the non parametric atlas registration framework we have recently developed in [6]. This technique derived from the optical flow model and the active contour framework allows to base the registration of an anatomical atlas on se ...

Extended focus optical coherence microscopy and fluorescence lifetime imaging

Theo Lasser, Rainer Leitgeb, Martin Villiger, Adrian Bachmann, Cédric Blatter

Fourier domain Optical coherence microscopy (FDOCM) offers excellent sensitivity and high axial resolution to image the structure of biological tissue. The depth information is extracted in parallel and allows very high volume acquisition rates. The presen ...

Femtosecond polarization relaxation in CdSe nanocrystals

Majed Chergui, Frank van Mourik, Awos Al Salman

We present ultrafast pump-probe studies on chem. prepd. CdSe nanocrystals. Upon pulsed optical excitation we find pronounced oscillations, indicating strong coupling to a LO phonon mode. From the polarization dependence of the signal addnl. information abo ...

Time-resolved imaging and spatially-resolved spectroscopy of Electrical Discharge Machining Plasmas

Christoph Hollenstein, Antoine Descoeudres, Ricardo Pérez Suárez

Optical spectroscopy of the emission from a plasma created during electrical discharge machining (EDM) showed a strong Ha line coming from neutral hydrogen atoms and continuum radiation. An electron temperature of 0.7 eV and plasma density of 2.1018 cm(3) ...

Light-induced spin crossover probed by ultrafast optical and X-ray spectroscopies

Majed Chergui, Andrea Cannizzo, Wojciech Gawelda, Van Thai Pham, Amal El Nahhas, Renske Marjan van der Veen

The photoinduced energy and structural relaxation of aq. iron(II)-tris-bipyridine ([FeII(bpy)3]2+), upon excitation into its singlet metal-to-ligand charge transfer (1MLCT) band, and the population of its short-lived (?0.6 ns) high-spin excited state have ...

BSLIM: Spectral Localization by Imaging with Explicit $ B _{ 0 } $ Field Inhomogeneity Compensation

Michaël Unser, Dimitri Nestor Alice Van De Ville, Ildar Khalidov, Mathews Jacob

Magnetic resonance spectroscopy imaging (MRSI) is an attractive tool for medical imaging. However, its practical use is often limited by the intrinsic low spatial resolution and long acquisition time. Spectral localization by imaging (SLIM) has been propos ...

Optical coherence tomography - high resolution imaging of structure and function

Rainer Leitgeb

There is no doubt that optical coherence tomography has become an important biomedical imaging tool today especially due to recent improvements in detection as well as fight source technology. OCT achieves resolution in tissue of a few micrometers and can ...
