READ ME File For Dataset 'PhD thesis "Nonlinear optical components and systems " AUTHOR: ALAN C. GRAY Associated PhD titled "Nonlinear optical components and systems for quantum technologies and communications" Dataset DOI: 10.5258/SOTON/D1759 ReadMe Author: Alan Gray, University of Southampton [ORCID https://orcid.org/0000-0002-2316-8821] AlanGrayPhD_data.xlsx contains data associated with the thesis title provided above. The spreadsheet contains the data for experimental chapters 4, 5, 6 and 7. Sets of data are labeled within the spreadsheet to indicate which figure they represent in the thesis. All data is ready for graphing using any commercial software capable of reading csv formatted data, except where clearly indicated. Chapter 4 figures: Mode field diamters of PPLN ridge waveguides alongside maximum conversion efficiency achieved. Chapter 5 figures: Investigation of waveguide uniformity. Figures alude to waveguide widths, propagation constants Chapter 6 figures: Upconversion telecommunications chapter. Data describes nonlinear conversion processes in experimental system and BERs associated. Chapter 7 figures: Simulation data contained within to enable a reader to reproduce figures using details and referenced papers,equations within the chapter. Experimental, raw-data optical spectra also added labelled for each analyte investigated.
