(eg Si-pos power 750 nm refers to power dependence measurements for the Si (+) helices performed at an incident wavelength of 750 nm) ----------------------------------------- Simulation: Files for each simulation are placed in folders describing the type of simulation (eg multipole, SHS). Individual files are named with the wavelength, nanohelix orientation and circular polarisation used. This dataset contains the experimental and simulation data for the titled manuscript. Experimental data included data for the power dependences, emission spectra, measured linear CD and calculated nonlinear g-factors and nonlinear CD from extinction. 2024-06-17 University of Bath public RightsHolder University of Bath Royal Society https://doi.org/10.13039/501100000288 RF\ERE\210172 Enhanced Research Expenses for URFs Royal Society https://doi.org/10.13039/501100000288 ICA\R1\201088 International Collaboration Awards of the RS - Clean Air Royal Society https://doi.org/10.13039/501100000288 RGF\EA\180228 Fellowship - Chirality in the 21st century: enantiomorphing chiral plasmonic meta/nano-materials Engineering and Physical Sciences Research Council https://doi.org/10.13039/501100000266 EP/T001046/1 UK National Quantum Technology Hub in Sensing and Timing Leverhulme Trust https://doi.org/10.13039/501100000275 RPG-2022-344 PERSEUS: molecular Polarizability Established by Rayleigh Scattering Enhancement and Ultra-Spectral analysis cent_photon Experimental data was recorded directly from the SR500 photon counter to a .txt file using LabView 2016 with a counting time of 5s. Data was imported into OriginPro2021 and organised. Medians were taken of the data and the resulting averages arranged to their corresponding scattering types (right angle, forward, RCP, LCP light) A mean of all data corresponding to a reference data for a given power was taken, and plotted as a function of measured power to give a curve. The averages for the second harmonic intensity is fitted against this curve to give an accurate average power ------------------------------------------------------------------------ Simulated data collected using Lumerical FDTD solver. For linear simulations, we extracted scattering and absorption cross sections from 6 power monitors surrounding the source and nanoparticle respectively. For the absorption 3D distribution, linear simulations provided absorption density in the nanoparticle which was then plotted in Matlab. For multipole solver, electromagnetic fields were extracted from 6 field profile monitors around the nanoparticle and from the refractive index profile monitor. These fields were then imported into MENP solver in MatLab (see link at end). Nonlinear simulations used chi 2 medium for the nanohelix and continuous wave normalisation was turned off. A high intensity fundamental field excited the nanohelix and near fields at second harmonic wavelength were measured by field profile monitors. Raw data files can be accessed using notepad or other program that can open .txt files. Files containing the graphs and processed data require OriginPro.
