Abstract
Silica glass optical fibers have revolutionized data transmission, sensing and laser development over the past 50 years, however, dielectric waveguides with a hollow core offer exciting development possibilities beyond traditional technology. Hollow Core Optical Fibers (HCFs) have been fabricated over the past 20 years with various geometries and refinements reported over this time. Despite numerous design developments and predictions from theoretical studies, one of the key performance indicators of optical fibers – attenuation - has remained significantly higher than can be routinely achieved in standard silica single mode fibers. Here we present recent developments in Nested Anti-resonant Nodeless Fiber (NANF) design over the last few years and show how this rapidly developing technology has been refined to produce state of the art HCFs with attenuation = 0.28 dB/km at 1550 nm.
