Raw data, RCWA code, COMSOL model for paper "Chiral resonant modes induced by intrinsic birefringence in lithium niobate metasurfaces"

The CSV files contain the raw data, which are used to generate Figures in the paper. LN_chiral_T.py is the python code for RCWA solver. All the transmission spectra in the paper are calculated based on LN_chiral_T.py. LN_chiral_modeanalysis.mph is a model of the COMSOL Multiphysics. The resonant frequencies and damping rates, electric field distributions, and optical chiral densities are simulated by using LN_chiral_modeanalysis.mph.In Figure 1, Fig1b.csv file is the raw data of Figure 1(b), calculated with LN_chiral_T.py. Fig1c_sim.csv and Fig1d_sim.csv are the raw data of the 'triangle maker' curves in Figure 1(c) and 1(d), which are generated from the LN_chiral_modeanalysis.mph. Fig1c_anal.csv and Fig1d_anal.csv are the raw data of the solid curves in Figure 1(c) and 1(d), which calculated using the Eq. (3) of the main text. Figure 1(e) is generated from the COMSOL model LN_chiral_modeanalysis.mph. In Figure 2, Fig2a.csv is the raw data of Figure 2(a), which are calculated using the Eq. (3) of the main text. Fig2b.csv is the raw data of Figure 2(b), which is generated from LN_chiral_modeanalysis.mph. Figure 2(c) is generated from the COMSOL model LN_chiral_modeanalysis.mph.In Figure 3, Fig3a.csv and Fig3b.csv are raw data of Figure 3(a) and Figure 3(b), which are calculated with RCWA code LN_chiral_T.py. Fig3c.csv and Fig3d.csv are raw data of Figure 3(c) and Figure 3(d), which are generated based on Figure 3(a) and Figure 3(b). Figure 3(e) is produced by LN_chiral_modeanalysis.mph. Fig3f.csv is the raw data of Figure 3(f), which is generated from LN_chiral_modeanalysis.mph.In Figure 4, Fig4b.csv and Fig4d.csv are raw experimental data of Figure 4(b) and Figure 4(d). Fig4c_blue.csv and Fig4c_red.csv are raw data of Figure 4(c), which is calculated based on Figure 4(b) and Figure 4(d).To run LN_chiral_modeanalysis.mph, COMSOL Multiphysics software with version 5.6 or higher should be installed. To run LN_chiral_T.py, rcwa solver S4 (https://web.stanford.edu/group/fan/S4/) should be installed.<br><br><br><br><br>
