High-Q and Compact Fabry-Perot Microresonators on Thin-Film Lithium Niobate
Likai Yang, Chunzhen Li, Jiacheng Xie +1
Thin-film lithium niobate (TFLN) has played a pivotal role in the advancement of integrated photonics, by supporting a diverse range of applications including nonlinear optics, ele…
Degeneracy-Locked Optical Parametric Oscillator
Fengyan Yang, Jiacheng Xie, Yiyu Zhou +4
Optical parametric oscillators (OPOs) are widely utilized in photonics as classical and quantum light sources. Conventional OPOs produce co-propagating signal and idler waves that…
High-efficiency, cryogenic-compatible grating couplers on an AlN-on-sapphire platform through bottom-side coupling
Yiyu Zhou, Mohan Shen, Chunzhen Li +2
Sapphire is a commonly used substrate for wide-bandgap III-nitride photonic materials. However, its relatively high refractive index results in low transmission efficiency in grati…
Fluorescence enabled phonon counting in an erbium doped piezo-optomechanical microcavity
Likai Yang, Jiacheng Xie, Hong X. Tang
Converting phonons to photons with optomechanical interaction provides a pathway to realize single phonon counting, which is instrumental in the quantum applications of mechanical…
Sub-terahertz optomechanics
Jiacheng Xie, Mohan Shen, Hong X. Tang
We demonstrate optomechanics in the sub-terahertz regime. An optical racetrack resonator, patterned from thin-film lithium niobate, is suspended to support mechanical structures os…
