Creating a switchable optical cavity with controllable quantum-state mapping between two modes
We describe how an ensemble of four-level atoms in the diamond-type
configuration can be applied to create a fully controllable effective coupling
between two cavity modes. The diamond-type configuration allows one to use a
bimodal cavity that supports modes of different frequencies or different
circular polarisations, because each mode is coupled only to its own
transition. This system can be used for mapping a quantum state of one cavity
mode onto the other mode on demand. Additionally, it can serve as a fast
opening high-Q cavity system that can be easily and coherently controlled with
laser fields.Comment: This is a pre-print of an article published in Scientific Reports.
