1Ultrabroadband and sensitive cavity optomechanical magnetometry显示文摘Magnetostrictive optomechanical cavities provide a new optical readout approach to room-temperature magnetometry.Here we report ultrasensitive and ultrahigh bandwidth cavity optomechanical magnetometers constructed by embedding a grain of the magnetostrictive material Terfenol-D within a high quality(Q)optical microcavity on a silicon chip.By engineering their physical structure,we achieve a peak sensitivity of26 p T∕Hz1/2 p comparable to the best cryogenic microscale magnetometers,along with a 3 d B bandwidth as high as 11.3 MHz.Two classes of magnetic response are observed,which we postulate arise from the crystallinity of the Terfenol-D.This allows single crystalline and polycrystalline grains to be distinguished at the level of a single particle.Our results may enable applications such as lab-on-chip nuclear magnetic spectroscopy and magnetic navigation.Bei-Bei Li George Brawley Hamish Greenall Stefan Forstner Eoin Sheridan Halina Rubinsztein-Dunlop Warwick P.Bowen 2020Photonics Research2020,8,7:4

3Sensitivity and Performance of Cavity Optomechanical Field Sensors显示文摘这篇文章详细为为洞 optomechanical 领域传感器建模描述一种技术。磁性的 A 或电场越过传感器导致一个空间地变化的压力,它然后在系统的机械 eigenmodes 上导致力量。每个振荡器上的力量当时能从在 magnetostrictive 应力和相应 eigenmode 之间的重叠积分是坚定的,与联合决定这力量能与被检测的最终的决定的强度的 optomechanical。而且,一个 optomechanical 磁场传感器为小型化以敏感和潜力与另外的磁场传感器相比。一个 optomechanical 传感器罐头潜在地超过类似的尺寸的最先进的磁强计,这被显示出,特别地另外的传感器基于 magnetostrictive 机制。Stefan FORSTNER Joachim KNITTEL Eoin SHERIDAN Jon D.
