ZnO as a platform for quantum photonics
Résumé
Quantum technologies are seen to be within reach for ripe applications with recent developments in quantum optics and photonics resulting into better control of quantum systems [1]. Many platforms, such as photonic crystals and cavities involving complex fabrications as well as many materials such as diamond or III-V semiconductors have been proposed for quantum photonics. We will report on a different material approach and in particular with the use of ZnO as a promising quantum photonics materials. Several aspects will be covered where we will show some results on using ZnO as a photonics material for guiding light and have a strong light-matter interaction with other quantum emitters. We will also show how ZnO nanowires (NWs) can be used as photodetectors and as such being integrated on optical circuits. Finally, we will develop why ZnO is interesting intrinsically for quantum technologies and in particular by manipulating and using defects within its band gap.
