Optimizing Hollow Core Fibers for Stable Interferometry

SummaryWe present a hollow core fiber (HCF) with optimized thickness of coating and silica glass, calculate its thermal sensitivity including the effect of coating and compare it with earlier-reported HCFs. We experimentally demonstrate the optimized HCF with thermal phase sensitivity as low as 1.64...

Description
Summary:SummaryWe present a hollow core fiber (HCF) with optimized thickness of coating and silica glass, calculate its thermal sensitivity including the effect of coating and compare it with earlier-reported HCFs. We experimentally demonstrate the optimized HCF with thermal phase sensitivity as low as 1.64 rad/K/m, which is 30 times below that of the standard single mode fiber.
