Abstract
The nonlinear epsilon-near-zero calculator (NLENZ) is a versatile tool that can calculate the nonlinear response of a free-carrier driven material for both IR and UV excitation conditions. Using fundamental band structures of materials such as ITO, XX:ZnO, XX:CdO, and XX:GaN, the nonlinear change in refractive index (or permittivity) can be calculated without any fitting parameters. This predictive tool can be used to model existing materials or as a forecasting tool for hypothetical, new materials. Included within the application are various calculations such as: band structure (E-k diagram), effective mass vs energy, linear permittivity vs wavelength, reflection, transmission and absorption vs wavelength, temporal dependence of nonlinearities, and wavelength dependence of nonlinearities. All the data is fully exportable and can be used in external simulations or to model experimental data.
