The thesis "Soliton dynamics in lithium niobate nano-waveguides" contains three research chapters with the majority of their content copied verbatim from three publications. These publications have their own archived datasets and so the majority of the research data from the thesis is contained within those pre-existing datasets. This dataset provides research data  for parts of the thesis that were not contained within those three publications and is therefore missing from the pre-existing datasets. Links to the three pre-existing datasets can be found in the 'Related datasets and code' section of this dataset.
