Read me file: University of Southampton – ORC – U. S Mutugala – usm1g14@soton.ac.uk The .csv files contains experimental and simulation data for the paper : Hollow-core fibres for temperature-insensitive fibre optics and its demonstration in an Optoelectronic oscillator Authors:U.S. Mutugala, E.R. Numkam-Fokoua, Y. Chen, T. Bradley, S. R. Sandoghchi, G. Jasion, R. Curtis, M.N. Petrovich, F. Poletti, D.J. Richardson, and R. Slavík In particular, data for the figures: Main manuscript Fig. 3(inset) spectral transmission characteristics of the fibre Main manuscript Fig. 4(a) Fibre temperature variation Main manuscript Fig. 4(b) Measured and expected OEO oscillating frequency change for three selected laser wavelengths of 1550 nm, 1609 nm and 1612 nm (two files) Main manuscript Fig. 4(c) Measured and prediction TCD characteristics of the fibre Main manuscript Fig. 5(a) Phase noise properties of the OEO at 1550 nm when the HC-PBGF was used as used as a delay line and when a standard optical fibre with similar delay was used as a delay line. Noise Floor is also shown. Main manuscript Fig. 5(b) Phase noise properties of the OEO at 1612 nm when the HC-PBGF was used as used as a delay line and when a standard optical fibre with similar delay was used as a delay line. Noise Floor is also shown. Supplementary information Fig. 1 Measured and simulated chromatic dispersion of the used HC-PBGF Date that the file was created: November 2018
