Optical spectroscopy of single- and two-ion transitions in an antiferromagnetic stoichiometric rare-earth crystal
Masaya Hiraishi, Gabrielle A. Hunter-Smith, Gavin G. G. King +5
We characterise optical transitions of neodymium ions (Nd3+) in antiferromagnetic neodymium gallate (NdGaO3) with applied fields up to 3 T. The magnetic phase of this material has…
Long optical coherence times and coherent rare earth-magnon coupling in a rare earth doped anti-ferromagnet
Masaya Hiraishi, Zachary H. Roberts, Gavin G. G. King +2
Rare-earth ions are characterised by transitions with very narrow linewidths even in solid state crystals. Exceedingly long coherence times have been shown on both spin and optical…
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…
Microwave-optical double resonance in a erbium-doped whispering-gallery-mode resonator
Li Ma, Luke S. Trainor, Gavin G. G. King +2
We showcase an erbium-doped whispering-gallery-mode resonator with optical modes that display intrinsic quality factors better than (linewidths less than 2 MHz), and couplin…
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…
