Fabrication and Characterization of 1-D diffusing elements

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim, Roland Andreas Bitterli

Certain high power laser applications require thin homogeneous laser lines. In this paper we describe the concept, fabrication and characterization of a 1-D diffuser that generates such a line. The device is based on an array of concave cylinder lenses wit ...

Miniaturized optical tweezer array with an array of reflective elements for reflecting the light back to a focal area

René Salathé, Guy Delacrétaz, Fabrice Merenda

Apparatus for forming a single or a plurality of threedimensional optical traps, the apparatus comprising: a. A collimated light source that is directed onto an array of focalizing refractive or diffractive elements providing a single or a plurality of foc ...

Refractive multiple optical tweezers for parallel biochemical analysis in micro-fluidics

René Salathé, Horst Arthur Vogel, Fabrice Merenda, Johann Rohner

We present a multiple laser tweezers system based on refractive optics. The system produces an array of 100 optical traps thanks to a refractive microlens array, whose focal plane is imaged into the focal plane of a high-NA microscope objective. This refra ...

Effects of cognitives abilities on metapopulation connectivity

Séverine Vuilleumier Varisco

Connectivity among demes in a metapopulation depends on both the landscape's and the focal organism's properties (including its mobility and cognitive abilities). Using individual-based simulations, we contrast the consequences of three different cognitive ...
