Low loss silica hollow core fibers for 3-4 μm spectral region

Opt Express. 2012 May 7;20(10):11153-8. doi: 10.1364/OE.20.011153.

Abstract

We describe a silica hollow-core fiber for mid-infrared transmission with a minimum attenuation of 34 dB/km at 3050 nm wavelength. The design is based on the use of a negative curvature core wall. Similar fiber designed for longer wavelengths has a transmission band extending beyond 4 µm.
