High numerical aperture silicon collimating lens for mid-infrared quantum cascade lasers manufactured using wafer-level techniques

Hans Peter Herzig, Lubos Hvozdara, Pierre-Yves Baroni, Joab Di Francesco, Antoine Muller

We present an aspheric collimating lens for mid-infrared (4-14 µ) quantum cascade lasers. The lenses were etched into silicon by an inductively coupled plasma reactive ion etching system on wafer level. The high refractive index of silicon reduces the heig ...

Microlenses with defined contour shapes

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

Ink-jet printing of optical ink over SU-8 pillars is here proposed as a technology for obtaining microlenses with shape control. To demonstrate the flexibility of this method, microlenses with five different contour shapes (ranging from circular and ellipt ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Jürgen Brugger, Edoardo Charbon, Vahid Fakhfouri, Dmitri Boiko, Joo Yeon Kim, Nils Benedict Brauer

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

Small-size microlens characterization by multiwavelength high-resolution interference microscopy

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Microlenses are widely studied in two main areas: fabrication and characterization. Nowadays, characterization draws more attention because it is difficult to apply test techniques to microlenses that are used for conventional optical systems. Especially, ...

Antireflective nanostructured microlenses

Hans Peter Herzig, Toralf Scharf, Pierre-Yves Baroni

Herein, a study of combining refractive microlenses arrays and nanostructured antireflective surfaces is presented. Fabrication method is surveyed for obtaining the hybrid surface with functionalities of refractive and antireflective (high-transmissive) el ...

Polymer multilayer photonic micro- and nanostructures with tailored spectral properties

Amazing and beautiful optical effects are present in Nature. Some examples are the iridescent colors produced by peacocks, butterflies and beetles. While the simulations of some of these structures have already been realized, only a few elements have been ...

Advanced passive micro-optical elements

Micro-optical elements are optical elements having size or details in the range of the micrometer scale. The emergency of such elements is strongly linked to the development made in the fabrication techniques during the nineties to follow the still actual ...

Refractive multiple optical tweezers for parallel biochemical analysis in micro-fluidics - art. no. 64830A

René Salathé, Horst Vogel, Fabrice Merenda, Johann Rohner, Jean-Marc Fournier

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 ...
