Anti-resonance, inhibited coupling and mode transition in depressed core fibers [PDF]

, 2020
The depressed core fiber (DCF), consisting of a low-index solid core, a high-index cladding and air surrounding, is in effect a bridge between the conventional step-index fiber and the tube-type hollow-core fiber from the point of view of the index ...

Trapping of Ultracold Atoms in a Hollow-core Photonic Crystal Fiber

, 2008
Ultracold sodium atoms have been trapped inside a hollow-core optical fiber. The atoms are transferred from a free space optical dipole trap into a trap formed by a red-detuned gaussian light mode confined to the core of the fiber.
