PhD topic and brief description

  • My PhD project concerns the conversion of microwave photons to optical photonics using cavity electro-optical coupling and is planned as a joint project with IBM. Integrated electro-optical converters have despite these appealing properties to date not been demonstrated, although in the past attempts have been made with bulk crystalline resonators. Prior work focused on bulk optical and microwave resonators, but did not achieve sufficiently large conversion rates. To overcome this challenge, and to enable sizeable electro-optical coupling, the proposed new underlying hybrid device architecture uses the large vacuum electric field offered by superconducting resonators. It confines electromagnetic modes to small volume and commonly exhibits high-Q, utilizing an integrated nonlinear optical microresonator on the same chip. The fabrication of microresonators from electro-optical materials is made possible via crystalline lithium niobate-on-insulator thin films, which allows to combine the large on-chip element density of integrated photonics with the second order nonlinearity of Lithium-Niobate.
