The control of light-matter interaction is an enabling technique for many emerging quantum technology applications. Photonic crystals (PhCs) are of particular interest since they can confine light in small mode volumes producing a strong interaction between light and emitters located in or near the cavity. Emitters such as lanthanide (Ln) molecules offer the potential of scalable quantum systems due to their characteristic narrow linewidth and wide emission spectrum.
This work focuses on the fabrication of PhCs by electron-beam lithography, inductively coupled plasma reactive ion etching and selective wet etching techniques and investigating different process parameters influencing the quality of PhCs. The morphological and optical properties of PhCs are characterized by scanning electron microscopy and micro-photoluminescence spectroscopy. In order to enhance the light emission, Ln molecules will be immobilized on the processed PhC cavities.
