Journal ArticleDOI
Comparing glass and plastic refractive microlenses fabricated with different technologies
Heidi Ottevaere,R. Cox,Hans Peter Herzig,Takaaki Miyashita,Kris Naessens,Mohammad R. Taghizadeh,Reinhard Völkel,H.j. Woo,Hugo Thienpont +8 more
TL;DR: In this article, the most important fabrication techniques for glass and plastic refractive microlenses and corresponding state-of-the-art micro-lenses, which were obtained from selected research groups, were reviewed and discussed.
Journal ArticleDOI
MT-compatible laser-ablated interconnections for optical printed circuit boards
G. Van Steenberge,Peter Geerinck,S. Van Put,J. Van Koetsem,Heidi Ottevaere,Danny Morlion,Hugo Thienpont,P. Van Daele +7 more
TL;DR: In this article, a parallel optical link over approximately 5 cm-long PCB integrated waveguides, fully connected using a standard MT-based connector, is demonstrated. And the authors show that laser ablation can be a key technology in optical board manufacturing to reach the stringent coupling tolerances.
Journal ArticleDOI
Signal processing challenges for digital holographic video display systems
David Blinder,David Blinder,Ayyoub Ahar,Ayyoub Ahar,Stijn Bettens,Stijn Bettens,Tobias Birnbaum,Tobias Birnbaum,Athanasia Symeonidou,Athanasia Symeonidou,Heidi Ottevaere,Colas Schretter,Colas Schretter,Peter Schelkens,Peter Schelkens +14 more
TL;DR: The steps needed to realize an end-to-end chain from digital content acquisition to display, involving the efficient generation, representation, coding and quality assessment of digital holograms are delineated.
Journal ArticleDOI
Fabrication of spherical microlenses by a combination of isotropic wet etching of silicon and molding techniques.
Jorge Albero,L. Nieradko,Christophe Gorecki,Heidi Ottevaere,Virginia Gomez,Hugo Thienpont,Juha Pietarinen,Birgit Päivänranta,Nicolas Passilly +8 more
TL;DR: A novel process technology of hemispherical shaped microlenses is reported, using isotropic wet etching of silicon in an acid solution to produce the microlense molds, which demonstrate high smoothness of the surfaces, excellent repeatability of mold fabrication and good optical properties.
Journal ArticleDOI
(Photo-)crosslinkable gelatin derivatives for biofabrication applications
Jasper Van Hoorick,Jasper Van Hoorick,Liesbeth Tytgat,Liesbeth Tytgat,Agnes Dobos,Heidi Ottevaere,Jurgen Van Erps,Hugo Thienpont,Aleksandr Ovsianikov,Peter Dubruel,Sandra Van Vlierberghe,Sandra Van Vlierberghe +11 more
TL;DR: A review paper elaborating on the different modification strategies and processing of gelatin is presented, with particular attention placed on the applied photoinitiators and the different biofabrication technologies including inkjet, extrusion or light-based technologies.
