- Title: Theory of Microwave-Optical Conversion Using Rare-Earth Ion Dopants
- Authors: Peter S. Barnett and Jevon J. Longdell
- Abstract summary: We develop a theoretical description of a device for coherent conversion of microwave to optical photons.
Dopant ions in a crystal are used as three-level systems, and interact with the fields inside overlapping microwave and optical cavities.
We develop a model for the cavity fields interacting with an ensemble of ions, and model the ions using an open quantum systems approach.

- Abstract: We develop a theoretical description of a device for coherent conversion of
microwave to optical photons. For the device, dopant ions in a crystal are used
as three-level systems, and interact with the fields inside overlapping
microwave and optical cavities. We develop a model for the cavity fields
interacting with an ensemble of ions, and model the ions using an open quantum
systems approach, while accounting for the effect of inhomogeneous broadening.
Numerical methods are developed to allow us to accurately simulate the device.
We also further develop a simplified model, applicable in the case of small
cavity fields which is relevant to quantum information applications. This
simplified model is used to predict the maximum conversion efficiency of the
device. We investigate the effect of various parameters, and predict that
conversion efficiency of above 80% should be possible with currently existing
experimental setups inside a dilution refrigerator.
