Dataset in support of the journal article 'Hollow-core fiber with stable propagation delay between -150°C and +60°C'

The dataset contains data underpinning the figures in the journal paper. The figures are as follows: Fig. 1: Calculated effective refractive index neff of the fundamental mode of the NANF-type HCF used in our experiments as a function of wavelength. Fig. 3: Measured TCD of a thinly coated HCF. For comparison, we also show reported data for low-TCD fibers from Furukawa, Linden Photonics, and Yangtze Optical FC, an SMF with standard acrylate coating (coated fiber diameter of 250 m), and an HCF with 75-m coating at temperatures above 60C. Fig.4: Measured phase thermal sensitivity of thinly coated HCF with the corresponding TCD shown on the right y axis. For comparison, previously reported measured data for bare HCF, HCF with 50-m, and extrapolated from 0 and 50-m data for a 10-m coated HCF are also shown.
