Predicting Structural and Optical Properties of Hollow-Core Photonic Bandgap Fibers from Second Stage Preforms

, 2013
We propose a simple theory based on mass conservation that allows accurate prediction of guidance properties in hollow-core photonic bandgap fibers (HC-PBGF) from knowledge of the second stage preforms from which the fibers are ...

Measurements of Group Delay and Chromatic Dispersion of Hollow-Core Fiber Using a Frequency Domain Method

Photonics
Although hollow-core fibers are intended to be single-mode, they can potentially carry slightly higher-order mode content depending on the specific fiber structure.
