Hollow-core fiber Characterization with Correlation-Optical Time Domain Reflectometry
arXiv:2204.06093 · doi:10.1364/OFC.2021.F4C.6
Abstract
Using a Correlation-OTDR, we characterized the temperature-induced group delay variations of two nested antiresonant nodeless hollow core fibers. The temperature sensitivity of both is substantially less than for SSMF with some dependency on coating type.
