DESCRIPTION:Speaker: Harald Schwefel\nhosted by Johannes Fink\nAbstract: Di
 electric whispering-gallery-mode resonators are a great tool to entrap ele
 ctro-magnetic radiation throughout the dielectrics transparency range1. I 
 will discuss hybrid systems which are resonant for both microwave and opti
 cal fields and that allow for second order nonlinear effects. In an effici
 ent resonant system and for strong microwave and optical fields\, sum- and
  difference frequency generation can cascade\, leading to optical frequenc
 y combs2. For the limit of very weak microwaves and only sum frequency gen
 eration\, coherent conversion of microwave signals allows the quantum stat
 e of individual microwave photons to be transferred into the optical domai
 n3\, useful for connecting future superconducting-qubits-based quantum-net
 works. In my talk I will discuss our current results and address future di
 rection including dual comb spectroscopy and quantum state conversion.1. N
