Dataset for Multi-core anti-resonant hollow core optical fibre

Data collection method:

For the transmission measurements, a single mode fibre (SMF-28) was used to couple into a single core, with collection from the single core ensured by using a large multi-mode fibre which matches the core size (AFS50/125Y). The data is given in columns of wavelength (in nm) and signal (in dBm, not calibrated). For each length, multiple cleaves were taken with the average used to calculate the transmitted signal. For the cutback, a similar method is used, but now the length is changed and the process is repeated. With the fibre loss being proportional to the length change. For the coupling experiment, the near field of the fibre was imaged using a DMK 23U445 monochrome camera with different exposures. The IC Capture camera utility software was used to control the exposure of the camera to generate the two images.

Technical details and requirements:

An Energetiq EQ-99X laser-driven white light source and ANDO Optical Spectrum Analyser were used, with SMF28-e and AFS50/125Y fibres used for coupling. A DMK 23U445 monochrome camera was used for the near field images. The scripts were run using MATLAB. Images are in TIFF and PNG formats.
