Abstract

This study was aimed to investigate the formation of thin films on a nanostructured surface. Optical characterization revealed the presence of Fano-like resonance phenomenon in such single-layer structure, surrounded by a lower refractive index media. Also, we demonstrate a 5 µm thick photonic multilayer structure composed of alternating high- and low-index materials, providing angular selectivity of light. The proposed 2D structure can be considered as a promising component for intracavity spatial filtering even in high power microlasers. Moreover, the possibility to control polarization with such photonic structures will be presented.
