Presentations

Stitching-Free 3D Printing of Millimeter-Sized Highly Transparent Spherical and Aspherical Optical Components (ATh1R.1)
Presenter: Simon Ristok, University of Stuttgart

We fabricate and characterize spherical and aspherical polymer lenses on the millimeter scale by stitching-free 3D printing via two-photon polymerization. The imaging quality is excellent, being comparable to commercially available glass lenses.

  Paper

3D Printed Hybrid Refractive/Diffractive Achromat and Apochromat for the Visible Wavelength Range (ATh1R.2)
Presenter: Michael Schmid, University of Stuttgart

We demonstrate 3D-printed hybrid refractive/diffractive achromats and apochromats by using DOEs and simultaneously combining two different photoresists. These combinations drastically reduce chromatic aberrations in 3D-printed micro optics for the visible wavelength range.

  Paper

From Single to Multi-Scaled Periodic Surface Structures: Towards Multifunctional Surfaces Using Laser Based Microfabrication Methods (ATh1R.3)
Presenter: Andrés Lasagni, Technische Universität Dresden

This study reports on the fabrication functionalized surfaces with enhanced properties using micro and nano-topographical features produced using laser based fabrication methods. By the combination of different structural elements, multifunctional surfaces are also produced.

  Paper

Electrospray Microthruster Based on Bessel-Beam Laser- Machined Microcapillaries Embedded in Glass (ATh1R.4)
Presenter: Brian Canfield, University of Tennessee Space Institute

We discuss fabrication and operation of robust, prototype electrospray microthrusters prepared in glass using Bessel-beam ultrafast laser micromachining. Electrospray of ionic liquid in vacuum is confirmed by measuring alternating currents with a Faraday cup.

  Paper

The Deepest Subwavelength LIPSS on ZnO by Reduction of the Damage Threshold (ATh1R.5)
Presenter: Yaoyao Liu, Nankai University

The smallest spatial period of LIPSS on ZnO monocrystal was achieved through metal/ZnO heterointerface assisted femtosecond laser processing. Simultaneously, the damage threshold of ZnO was decreased by 54% due to the metal film coating.

  Paper

Ultrafast Self-Assembling of Quasi-Hexagonal Periodic Surface Structures on a Sapphire Crystal (ATh1R.6)
Presenter: Iaroslav Gnilitskyi, "NoviNano Lab" LLC


We report generation of quasi-hexagonal microstructures of variable shape on a surface of crystalline sapphire wafer by scanning multiple 266-femtosecond laser pulses at wavelength 1030 nm. Mechanisms and potential applications of the microstructures are discussed.

  Paper

Design and Fabrication of 3D Interconnects for Photonic Neuronal Networks Using Two-Photon Polimerization (ATh1R.7)
Presenter: Ricardo Adão, INL - Int. Iberian Nanotech. Lab.

Photonic neuromorphic networks composed of spiking nanolight sources require novel approaches for compact and efficient optical interconnection. We design, simulate and fabricate 3D polymer waveguides and obtain promising elevated structures suited for complex waveguide crossings
