PHENOmenon in Photonics West 2020

General Moscone Center, San Francisco, USA

Several partners of the PHENOmenon project showed results and developments from the project in one of the most important conference and fair on Photonics worldwide.


Many of the researchers in PHENOmenon met this week in the Photonics West SPIE conference and Fair, one of the largest in the world in the field of advanced photonics applications. AIMEN, CNRS, MPO, ICFO, CDA, IMT-A, ... many of our partners were present at the fair and conferences (LASE, BIOS, OPTO, ...), and we would like to highlight the following presentations:



INVITED PAPER FROM MPO IN THE 3D MICRO-NANOPRINTING SESSION. 

Industrial use of high precision 3D printing 
Author(s): Benedikt Stender, Fabian Gumpert, Jonas Wiedenmann, Willi Mantei, Yannick Dupuis, Alexander Krupp, Fabian Hilbert, Ruth Houbertz, Multiphoton Optics GmbH (Germany) 

Industrial use of High-Precision 3D Printing via two-photon absorption (TPA) requires high structure homogeneity at a reproducible level. Although still mainly used in academia, the interest for industrial application is continuously increasing. For this purpose, a novel fabrication strategy for scalable fabrication will be presented. Additionally, reproducibility in structure formation will be analyzed for selected elements with respect to overall size, angle generation and lens characteristics. The results demonstrate both scalable processes and high reproducibility provided by a stable process during fabrication.


PRESENTATION IN THE LASER 3D MANUFACTURING SESSION: DLW- HIGH SPEED PRINTING

Impact of massive parallelization on two-photon absorption micro- and nanofabrication 

Author(s): Fabian Hilbert, Jonas Wiedenmann, Benedikt Stender, Willi Mantei, Ruth Houbertz, Multiphoton Optics GmbH (Germany); Quentin Carlier, Luis A. Perez Covarrubias, Kevin Heggarty, IMT Atlantique Bretagne-Pays de la Loire (France); Caroline Arnoux, Cyrille Monnereau, Patrice Baldeck, Ecole Normale Supérieure de Lyon (France) 

The use of polymerization via two-photon absorption (TPA), also known as High-Precision 3D Printing, is gaining increasing attraction. Since TPA is a scanning technology, industrial throughput fabrication can be achieved either by intelligent fabrication strategies and an excellent material basis, but also by multi-spot exposure strategies. Massive parallelization is demonstrated, which was realized by beam splitting diffractive optical elements (DOE). Simultaneous fabrication with more than 100 focal spots will be reported. With this approach, micro- and nanostructures are fabricated and application possibilities for metaoptics will be illustrated. Important aspects like scan speed and laser power will be addressed.
