Transflective holographic film for head worn display

Jürgen Brugger, Victor Javier Cadarso Busto, Christophe Moser, Jonas Grossenbacher, Eric Tremblay

A display panel assembly comprises a transflective holographic screen, i.e., a transparent screen that reflects light from a projection system, comprising at least a volume hologram, a first protective element and a second protective element, each arranged ...

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

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

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. ...

PDMS-based, magnetically actuated variable optical attenuators obtained by soft lithography and inkjet printing technologies

Jürgen Brugger, Victor Javier Cadarso Busto

This paper reports and compares the implementation of magnetic variable optical attenuators (M-VOA) by two fabrication strategies. In the first case, a two-layer structure containing a non-doped polydimethylsiloxane (PDMS) layer on a magnetic PDMS (M-PDMS) ...

Inkjet printed superparamagnetic polymer composite hemispheres with programmed magnetic anisotropy

Jürgen Brugger, Massimo Mastrangeli, Victor Javier Cadarso Busto, Christofer Hierold, Loïc Jacot-Descombes, Rosario Maurizio Gullo, Berna Ayse Özkale Edelmann

We present the fabrication and characterization of large arrays of inkjet-printed superparamagnetic polymer composite (SPMPC) hemispherical microstructures. SPMPCs are appealing for applications in microsystems and nanorobotics due to the added functionali ...

Curved Holographic Combiner for Color Head Worn Display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher, Arnaud Mader, Seyedpayam Vahdati

A volume hologram recorded with a lens array is proposed as a color transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a single MEMS-based projector is efficiently diffracted t ...

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

Jürgen Brugger, Victor Javier Cadarso Busto, Thomas Kiefer, 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 ...
