Dataset for "Guidance of ultraviolet light down to 190 nm in a hollow-core optical fibre"

The data archived here is the raw data for the characterisation of a hollow core anti-resonant fibre designed to guide in the ultraviolet wavelength range. Measurement of attenuation and bend loss were performed and the code used to process the raw data is also provided.

From 1 August 2023 to 4 August 2023

Documentation

Data collection method:

For the cutback measurements, the transmission through a long length of fibre was taken and then the length of the fibre was reduced and the transmission was taken again with no change in the input coupling. For bend loss, the transmission through a large loop ~ 45 cm diameter was taken and then the fibre was wound into 5 loops of smaller radius and the new transmission recorded. In both cases two output cleaves were performed at each stage.

Technical details and requirements:

Equipment used: custom built Bentham monochromator, EQ-99X LDLS from Energetiq/Hamamatsu. The MATLAB code is known to work with release R2023a.

Additional information:

The data files (*.dat) are plain text files containing tab delimited columns. These columns are arranged into pairs, where the first column is wavelength in nanometres and the second is signal in nanoamps. In the files in the Cutbacks folder, the first four column-pairs are signal through fibre, while the last column-pair is a background scan. In the files in the Bend loss folder, the first two column-pairs are a large bend radius; the next two are the radius as given in the filename (e.g '6cm'); and the final column-pair is the fibre returned to the large bend radius.
