Journal ArticleDOI
Integration of micrometer-sized polymer elements at the end of optical fibers by free-radical photopolymerization
TL;DR: A simple method of manufacturing micrometer-sized polymer elements at the extremity of both single-mode and multimode optical fibers is reported and it is shown that the tip geometry can be adjusted by the variation of basic parameters such as the geometry of the deposited drop and the conditions of drop illumination.
Journal ArticleDOI
Fabry-Perot refractometer based on an end-of-fiber polymer tip.
Orlando Frazão,Paulo Caldas,Jose Luis Santos,Paulo Marques,Colette Turck,Daniel-Joseph Lougnot,Olivier Soppera +6 more
TL;DR: A micrometric Fabry-Perot refractometer based on an end-of-fiber polymer tip is proposed, which is coherence addressed and heterodyne interrogated, resulting into a liquid refractive index resolution of approximately 7.5x10(-4).
Journal ArticleDOI
Spatially controlled synthesis of silver nanoparticles and nanowires by photosensitized reduction

TL;DR: The present paper reports on the spatially controlled synthesis of silver nanoparticles (NPs) and silver nanowires by photosensitized reduction by direct photogeneration and a photochemically assisted procedure allowing silver to be deposited at the surface of a polymer microtip.
Journal ArticleDOI
Dry photopolymer films for computer-generated infrared radiation focusing elements
TL;DR: The formation of a surface wave of the monomer along the light-darkness boundary is observed for the first time to the authors' knowledge and confirms the previously proposed thermodynamic model of the mechanism of the hologram formation in photopolymerizable layers.
Journal ArticleDOI
PEW: Photopolymerization by evanescent waves. II. Revealing dramatic inhibiting effects of oxygen at submicrometer scale
TL;DR: In this paper, it was shown that the properties of the material and the chemistry of the system also have to be taken into account to fit the experiments more precisely, and evidence was provided that dissolved oxygen has a marked effect on gel dose.
