Narrowband and high-rate entangled photon-pair generation from a high-Q silicon microring resonator
Shoichiro Yasui, Tomohiro Inaba, Hidetaka Nishi +4
Entangled photon-pair sources are indispensable building blocks of quantum information processing technologies. Among the available approaches, on-chip microresonators are particul…
High-gain optical amplification and lasing from erbium-doped single-crystal films epitaxially grown on silicon
Xuejun Xu, Tomohiro Inaba, Takuma Aihara +3
On-chip erbium-doped optical amplifiers and lasers are essential for realizing fully integrated active silicon photonic circuits, but their performance has been limited by the low…
Coherent response of inhomogeneously broadened and spatially localized emitter ensembles in waveguide QED
Lewis Ruks, Xuejun Xu, Ryuichi Ohta +2
Spectrally and spatially varying ensembles of emitters embedded into waveguides are ever-present in both well-established and emerging technologies. If control of collective excita…
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…
