Triply Resonant Microwave to Optical Conversion in Erbium-170 Doped Yttrium Orthosilicate
Gavin G. G. King, Luke S. Trainor, Jevon J. Longdell
We report microwave to optical upconversion in isotopically purified erbium-doped yttrium orthosilicate in a Fabry-Pérot resonator at millikelvin temperatures. This follows on from…

Probing Strong Coupling between a Microwave Cavity and a Spin Ensemble with Raman Heterodyne Spectroscopy
Gavin G. G. King, Peter S. Barnett, John G. Bartholomew +2
Raman heterodyne spectroscopy is a powerful tool for characterizing the energy and dynamics of spins. The technique uses an optical pump to transfer coherence from a spin transitio…

Ultrastrong coupling between a microwave resonator and antiferromagnetic resonances of rare earth ion spins
Jonathan Everts, Gavin G. G. King, Nicholas Lambert +3
Quantum magnonics is a new and active research field, leveraging the strong collective coupling between microwaves and magnetically ordered spin systems. To date work in quantum ma…
