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…
Symmetric Second-Harmonic Generation in Sub-wavelength Periodically Poled Thin Film Lithium Niobate
Fengyan Yang, Juanjuan Lu, Mohan Shen +2
Second harmonic generation (SHG) extensively employs periodically poled nonlinear crystals through forward quasi-phase-matching to achieve efficient frequency conversion. As poling…
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…
