Optically-resonant nanostructure-based systems for spectral selectivity

This thesis presents two different approaches for spectrally-selective nanostructure-based systems with their specific advantages and disadvantages; see Chapter 1 for spectrally-selective Mie-resonant metasurfaces, and Chapter 2 for nanostructure-modulated FP resonators. Furthermore, to bridge the gap between fundamental science and industry, novel fabrication techniques laser-induced tailoring and structuring of metasurfaces are presented; see Chapter 3. All things considered, this work is not intended to revolutionize optics. Still, it is written with a bit of hope to put a small step in the development of nanophotonics and its applicability in real-world applications.
