The future of photonic devices involves harnessing non-linear effects, for applications such as frequency upconversion and down-conversion, optical switching, and emission control. To effectively do this, the optical properties of designed material systems are needed. Hyperbolic metamaterials that use both conductors and dielectrics have been shown to have enhanced non-linear properties near the topological transition point. Creating that topological transition point in a layered hyperbolic metamaterial offers a way to control the non-linear properties without a complicated 3D design. Layered 1D metamaterials still have a large enough design space to achieve various non-linear effects across a large frequency range and have a relative ease of fabrication. For this research, ITO was chosen as the conductor, which has advantages due to its ready availability and CMOS compatibility. The chosen dielectric, SiO2, is also easily available. The non-linear properties of the hyperbolic metamaterials were modeled with an efficient Matlab code, and the results show the capability of controlling the non-linear properties and optimizing for many different possible applications.
