We have investigated the doping mechanism of pentacene with iodine and its impact on the structure and on the electronic properties of single crystals, powders, and thin films in a large range of iodine concentration up to six iodine per pentacene (PEN) mo ...
Photonic crystals are periodic dielectric structures, where the periodicity varies on the wavelength scale. Analogous to electrons in semiconductors, the photon propagation can be described using a band structure in which transmission bands are separated b ...
We present two methods based on the analysis of Fabry-Perot interference for a detailed characterization of a 90degrees corner in a two-dimensional photonic crystal waveguide fabricated in a thin Si membrane. These methods are a means of identifying the cr ...

We present a new technique for computing the electromagnetic field that propagates and is scattered in three-dimensional structures formed by bodies embedded in a stratified background. This fully vectorial technique is based on the Green's tensor associat ...
Regular periodic structures with large refractive index contrast are often called photonic crystals and may exhibit photonic bandgap behaviour. Planar waveguide 2D and 1D periodic microstructures exhibiting photonic bandgap behaviour are likely to be usefu ...
The influence of static disorder on the optical properties of microcavity-embedded quantum wells is studied by means of a microscopic model. Both the exciton-photon coupling and the exciton-disorder interaction are treated nonperturbatively. Despite the no ...
