Coherent conversion between microwave/ THz and optical photons

Image from Licence Details: Coherent conversion between microwave/ THz and optical photons

Application: Quantum computing, photonic communications, signal processing, sensing and measurements, terahertz imaging.

Features Benefits
  • The technology utilises highly excited Rydberg states in the alkali atoms to convert millimetre waves into optical radiation and vice versa.
  • No need for microfabrication or microcavities, saving cost.
  • Reduced limits on bandwidth and tunability.
  • Phase coherent interconversion between microwave and optical radiation. Maximally achievable conversion efficiency of almost 100%.
  • Much higher conversion efficiencies than other optical to microwave radiation converters.
  • Provides a route to freely scalable all-photonic quantum computers.
  • Interconversion of any temporal/spectral shape of signal, up to a bandwidth of 100 MHz.
  • Allows conversion of arbitrarily multiplexed signals, with the same conversion efficiency for each letter in the encoding alphabet.
  • Spatial and spectral multimode conversion.
  • Can be used to convert arbitrary time-series and enables microwave and terahertz imaging.
  • Can select the microwave carrier frequency from the available transitions in the Rydberg manifold.
  • Gives a choice of bands from 1 GHz up to several THz.
