Dataset supporting the paper: Graphene Plasmonic Waveguides for Mid-Infrared Supercontinuum Generation on a Chip

Data collection method:

Guided modes (electric field profiles, effective indeces) have been computed with the help of Comsol Multiphysics (http://www.comsol.com/) commercial Maxwell solver (version 5.1). The pulse propagation equation was solved with the help of Matlab, by using the well established split-step algorithm, full details of the algorithm are available in G.P. Agrawal, "Nonlinear Fiber Optics," 5th ed. (Academic Press, 2013).

Additional information:

In Fig1_data.csv, the grid parameters are x: (-15:0.1:15) nm; y: (-15:0.1:15) nm. All electric field components are in SI units (V/m). In Fig2a_data.csv (effective indexes of waveguide modes), the first column gives values of the wavelength in µm, columns 2-5 give results for GSP mode without waveguide, and modes in waveguides of widths 5 nm, 15 nm and 25 nm, respectively. In Fig2b_data.csv (attenuation length of waveguide modes), the first column gives values of the wavelength in µm, columns 2-5 give the length in µm for GSP mode without waveguide, and modes in waveguides of widths 5 nm, 15 nm and 25 nm, respectively. In Fig2b_data_FEM.csv (attenuation length of the guided mode in the w=25nm wide waveguide as computed from COMSOL), the first column gives values of the wavelength in µm, and the second column gives the attenuation length in µm. In Fig2c_data.csv (nonlinear coefficient gamma, in 1/(mW nm), of waveguide modes), the first column gives values of the wavelength in µm, columns 2-4 give gamma values for waveguides of widths 5 nm, 15 nm and 25 nm, respectively. In Fig2d_data.csv (maximal ratio L_p/L_{nl} of waveguide modes), the first column gives values of the wavelength in µm, columns 2-4 give gamma values for waveguides of widths 5 nm, 15 nm and 25 nm, respectively. In Fig3_data.csv, the first column gives values of the wavelength in µm, columns 2-5 give power (in dB) for the input pulse, and outputs for peak power P_0=1µW, P_0=20µW and P_0=500µW, respectively.
