Observation of Acoustically Induced Dressed States of Rare-Earth Ions
Ryuichi Ohta, Gregoire Lelu, Xuejun Xu +9
Acoustically induced dressed states of long-lived erbium ions in a crystal are demonstrated. These states are formed by rapid modulation of two-level systems via strain induced by…
Rare-earth-mediated opto-mechanical system in the reversed dissipation regime
Ryuichi Ohta, Loïc Herpin, Victor M. Bastidas +3
Strain-mediated interaction between phonons and telecom photons is demonstrated using excited states of erbium ions embedded in a mechanical resonator. Owing to the extremely long-…
Strain-induced exciton decomposition and anisotropic lifetime modulation in a GaAs micromechanical resonator
Ryuichi Ohta, Hajime Okamoto, Takehiko Tawara +2
We demonstrate mechanical modulations of the exciton lifetime by using vibrational strain of a gallium arsenide (GaAs) resonator. The strain-induced modulations have anisotropic de…
