3D Printed Micro-Optics for Biophotonics

Autor: Bertoncini, Andrea

3D printing, also known as ”additive manufacturing”, indicates a set of fabrication techniques that build objects by adding material, typically layer by layer. The main advantages of 3D printing are unlimited shapes and geometry, fast prototyping

Miniature 120-beam coherent combiner with 3D printed optics for multicore fiber based endoscopy

Autor: Sivankutty, Siddharth, Bertoncini, Andrea, Tsvirkun, Victor, Kumar, Naveen Gajendra, Brévalle, Gaelle, Bouwmans, Géraud, Andresen, Esben Ravn, Liberale, Carlo, Rigneault, Hervé

We report high efficiency, miniaturized, ultra-fast coherent beam combining with 3D printed micro-optics directly on the tip of a multicore fiber bundle. The highly compact device foot-print (180 micron diameter) facilitates its incorporation into a

3D-Printed Photocathodes for Resonant, Terahertz-Field-Driven Ultrafast Electron Emission

Autor: Rovere, Andrea, Piccoli, Riccardo, Bertoncini, Andrea, Jeong, Young-Gyun, Payeur, Stéphane, Vidal, François, Lee, Seung-Heon, Seok, Jin-Hong, Kwon, O-Pil, Morandotti, Roberto, Liberale, Carlo, Razzari, Luca

Ultrashort photoemitted electron bunches can provide high electron currents within sub-picosecond timeframes, enabling time-resolved investigations of ultrafast physical processes with nanoscale resolution. Non-resonant conductive nanotips are typica

3D printed waveguides based on Photonic Crystal Fiber designs for complex fiber-end photonic devices

Autor: Bertoncini, Andrea, Liberale, Carlo

Optical waveguide segments based on geometrically unbound photonic crystal fibers (PCF) designs could be exploited as building blocks to realize miniaturized complex devices which implement advanced photonic operations. Here, we show how to fabricate
