Organic-inorganic-hybrid-polymer microlens arrays with tailored optical characteristics and multi-focal properties

Jürgen Brugger, Loïc Jacot-Descombes, Victor Javier Cadarso Busto

Plano-convex microlens arrays of organic-inorganic polymers with tailored optical properties are presented. The fine-tuning of each microlens within an array is achieved by confining inkjet printed drops of the polymeric ink onto pre-patterned substrates. ...

Direct imprinting of organic-inorganic hybrid materials into high aspect ratio sub-100 nm structures

Jürgen Brugger, Thomas Kiefer, Victor Javier Cadarso Busto, Vaida Auzelyte

The challenging fabrication of sub-100-nm structures with high aspect ratio by UV-nanoimprint lithography (NIL) is addressed in this work. Thermal shrinkage is induced by cooling the structures below room temperature to avoid the issues commonly arising du ...

Polymeric variable optical attenuators based on magnetic sensitive stimuli materials

Jürgen Brugger, Victor Javier Cadarso Busto

Magnetically-actuable, polymer-based variable optical attenuators (VOA) are presented in this paper. The design comprises a cantilever which also plays the role of a waveguide and the input/output alignment elements for simple alignment, yet still renderin ...

Microdrop generation and deposition of ionic liquids

Jürgen Brugger, Victor Javier Cadarso Busto

This work describes the use of a piezo-actuated inkjet print head with a nozzle aperture of 50 mu m to obtain picoliter drops of different model ionic liquids (ILs). A theoretical analysis of the microdrop generation of three model ILs is confirmed by expe ...

Inkjet-printed SU-8 Hemispherical Microcapsules and Silicon chip Embedding

Jürgen Brugger, Loïc Jacot-Descombes, Victor Javier Cadarso Busto, Rosario Maurizio Gullo, Massimo Mastrangeli

Planar lithography techniques are not effective for precise fabrication of microdevices with hemispherical shapes. Drop-on-demand (DOD) inkjet printing (IJP) of photo-curable ink is a more appropriate fabrication approach as it takes advantage of the surfa ...

High-resolution 1D moirés as counterfeit security features

Roger Hersch, Sylvain Chosson, Jürgen Brugger, Katrin Sidler Arnet, Victor Javier Cadarso Busto

A moire is an interference pattern that appears when two different periodic structures are overlaid. The image created is extremely sensitive to small variations in the original layers and is thus very interesting for anti-counterfeit protection. We presen ...
