Optofluidics

"Optofluidics" is the marriage of optics, optoelectronics and nanophotonics with fluidics. Such integration represents a new approach for dynamic manipulation of optical properties at length scales both greater than and smaller than the wavelength of light ...

Synthesis and Optical Properties of Water-Soluble NIR Absorbing Star Polypeptides based on Functional Rylene Dyes

Harm-Anton Klok

In this contribution, the synthesis of two novel amino-functionalized terrylene and quaterrylene diimide derivatives is described. These chromophores have been used as initiators for the ring-opening polymerization of N€-benzyloxycarbonyl-L-lysine N-carbox ...

Growth and Optical Characterization of Dense Arrays of Site-Controlled Quantum Dots Grown in Inverted Pyramids

Elyahou Kapon, Benjamin Dwir, Klaus Leifer, Martin Henrik Baier

We report on the growth and optical properties of dense arrays of single GaAs/AlGaAs quantum dot (QD) heterostructures with pitches as small as 300 nm. The samples were grown by organometallic chemical vapor deposition in dense inverted pyramids on {1 1 1} ...

Nontrivial carrier recombination dynamics and optical properties of over-excited GaN/AlN quantum dots

Nicolas Grandjean

We analyze the low temperature photoluminescence properties of two multi-layer stacking of GaN/AlN quantum dots. We report drastic differences of linewidths between continuous wave and time-resolved photoluminescence experiments. After the pulsed excitatio ...

Depolarization effects of light reflected by domain-structured cholesteric liquid crystals

Toralf Scharf

The simulation of light reflected by polymer-dispersed cholesteric liquid crystals is carried out using a model that takes into account the domain structure of the layer. The model is based on the 4×4 matrix calculation method of Berreman. One considers di ...

A novel non-diffractive reconstruction method for digital holographic microscopy

Michaël Unser, Christian Depeursinge, Etienne Cuche, Thierry Blu, Pierre Marquet

We present a new method for reconstructing digitally recorded off-axis Fresnel holograms. Currently-used reconstruction methods are based on the simulation and propagation of a reference wave that is diffracted by the hologram. This procedure introduces ...

Synchrotron radiation total reflection X-ray fluorescence and energy dispersive X-ray fluorescence analysis on AP1 (TM) films applied to the analysis of trace elements in metal alloys for the construction of nuclear reactor core components: a comparison

Synchrotron radiation induced total reflection X-ray fluorescence (TXRF) and conventional 45 degrees energy dispersive X-ray fluorescence analysis (EDXRF) using a 150-nm-thick AP1 (TM) film as sample carrier have been exploited for the elemental analysis o ...

Optical spectral probing for epithelial tissue characterisation

Philippe Thueler

In this thesis, a new method has been developed, which determines the optical coefficients spectra (absorption and scattering) of small volumes of tissue (1 mm3) by the measurement of spatially resolved reflectance between 480 and 950 nm. Firstly, an algor ...
