Tapered multi-core fiber for lensless endoscopes
Fatima El Moussawi, Matthias Hofer, Damien Labat +7
We present a novel fiber-optic component, a "tapered multi-core fiber (MCF)", designed for integration into ultra-miniaturized endoscopes for minimally invasive two-photon point-sc…

Flexible lensless endoscope with a conformationally invariant multi-core fiber
Viktor Tsvirkun, Siddharth Sivankutty, Karen Baudelle +5
The lensless endoscope represents the ultimate limit in miniaturization of imaging tools: an image can be transmitted through a (multi-mode or multi-core) fiber by numerical or phy…

Nonlinear imaging through a golden spiral multicore fiber
Siddharth Sivankutty, Viktor Tsvirkun, Olivier Vanvincq +3
We report two-photon lensless imaging through a novel golden spiral multicore fiber. This unique layout optimizes the sidelobe levels, field of view, cross-talk, group delay and mo…
