In the area of optoelectronics, Epsilon Near Zero (ENZ) materials possess a special place, as due to them, high nonlinearities can be achieved. Our interest is focused at the telecommunication wavelengths, as a lot of nanophotonic phenomena are taking place. Transparent Conductive Oxides (TCOs) is a group of materials that are used in the ENZ regime. Aluminum Zinc Oxide (AZO) is a TCO that has been proved that is preferred for telecom applications. In order to achieve higher nonlinearities in ENZ regime, we fabricate 3D photonic nanostructures, via Multiphoton lithography and we cover them with AZO via Pulsed Laser Deposition.
