Multi-core anti-resonant hollow core optical fiber

Optics Letters
We report the fabrication and characterization of a multi-core anti-resonant hollow core fiber with low inter-core coupling. The optical losses were 0.03 and 0.08 dB/m at 620 and 1000 nm, respectively, while the novel structure provides new insights into hollow core fiber design and fabrication.

Flexible lensless endoscope with a conformationally invariant multi-core fiber [PDF]

, 2019
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 physical inversion of the fiber's pre-measured transmission matrix.
