Code and data for "Contrast ceiling and bandwidth–thickness product of optically pumped superconducting-film terahertz modulators"

Python code and numerical results for the manuscript "Contrast ceiling and bandwidth–thickness product of optically pumped superconducting-film terahertz modulators". The archive contains the model of optically pumped NbN films on MgO and sapphire (thin-film pump optics at 800 nm, two-pool excitation kinetics with the measured density dependence of the recovery, BCS conductivity with a finite pair-conserving scattering rate, terahertz transmission and mount heating), the comparison with digitized published kinetics, the single-pulse, pulse-train and pseudo-random-bit calculations, the closed-form contrast–loss front and bandwidth–thickness product, the scripts that produce Figs. 1–7, and the source data of every figure as CSV files. README.md lists which script produces which result.
