Journal ArticleDOI
Optimized optomechanical crystal cavity with acoustic radiation shield
TL;DR: In this article, the design of an optomechanical crystal nanobeam cavity that combines finite-element simulation with numerical optimization is presented, and considers the optomchanical coupling arising from both moving dielectric boundaries and the photo-elastic effect.
Journal ArticleDOI
Two-Dimensional Phononic-Photonic Band Gap Optomechanical Crystal Cavity
Amir H. Safavi-Naeini,Jeff T. Hill,Seán M. Meenehan,Jasper Fuk-Woo Chan,Simon Gröblacher,Oskar Painter +5 more
TL;DR: An engineered defect in the crystal structure is used to localize optical and mechanical resonances in the band gap of the planar crystal, creating an artificial crystal structure that has a full phononic band gap for microwave X-band phonons and a two-dimensional pseudo-band gap for near-infrared photons.
Journal ArticleDOI
Phonon counting and intensity interferometry of a nanomechanical resonator
Justin D. Cohen,Seán M. Meenehan,Gregory S. MacCabe,Simon Gröblacher,Amir H. Safavi-Naeini,Francesco Marsili,Matthew D. Shaw,Oskar Painter +7 more
TL;DR: An optical probe and single-photon detection is used to study the acoustic emission and absorption processes in a silicon nanomechanical resonator, and a measurement similar to that used by Hanbury Brown and Twiss is performed to measure correlations in the emitted phonons as the resonator undergoes a parametric instability formally equivalent to that of a laser.
Journal ArticleDOI
Diamond optomechanical crystals
Michael J. Burek,Justin D. Cohen,Seán M. Meenehan,Nayera El-Sawah,Cleaven Chia,Thibaud Ruelle,Srujan Meesala,Jake Rochman,Haig A. Atikian,Matthew Markham,Daniel J. Twitchen,Mikhail D. Lukin,Oskar Painter,Marko Loncar +13 more
TL;DR: In this article, the authors demonstrate diamond optomechanical crystals (OMCs), a device platform to enable such applications, wherein the co-localization of ∼200 THz photons and few to 10 GHz phonons in a quasi-periodic diamond nanostructure leads to coupling of an optical cavity field to a mechanical mode via radiation pressure.
Journal ArticleDOI
Pulsed Excitation Dynamics of an Optomechanical Crystal Resonator near Its Quantum Ground State of Motion
Seán M. Meenehan,Justin D. Cohen,Gregory S. MacCabe,Francesco Marsili,Matthew D. Shaw,Oskar Painter +5 more
TL;DR: Using pulsed optical excitation and read-out along with single-phonon counting techniques, the authors measured the transient backaction, heating, and damping dynamics of a nanoscale silicon optomechanical crystal cavity mounted in a dilution refrigerator at a base temperature of T_f ≈ 11
