Frequency Conversion of Photons

Project objective

Challenge in the realisation of quantum networks based on trapped ions is the mismatch between wavelengths of ion emission and the transmission of conventional optical fibres. We introduce a “photonic gear-box”, which will coherently change the wavelength of photons emitted by trapped ions from near-UV to IR. 



  • Identified suitable material platforms
  • Accomplished numerical simulations of various structures
