SLAM - Squeezed Light quAntum MEMS Gravimeter

格拉斯哥大学的研究人员已经在所有智能手机的陀螺仪上使用了相同的微电子机械系统(MEMS)技术制造了弹簧上的硅制造质量，并将灵敏度提高了5000倍。这种MEMS重力仪有可能用于寻找新的石油和天然气研究，快速找到埋藏的设施，从而减少道路工程，并为火山喷发提供早期预警。该项目的目标是提供一种具有相关光子对的量子压缩光源，用于测量MEMS重力仪的输出，将灵敏度提高到40倍。该项目涉及开发一种可以探测单光子的光电探测器，该探测器还具有在可以透过雨、雾和雾的波长下进行测距(通过反射光子并对其返回进行计时)的应用。一个关键目标是确保英国的供应链，使用IQE为单光子探测器和OptoCap提供商业硅外延GE，并生产带有光纤通道的芯片级真空封装，这些组件是MEMS重力仪的关键部件。

"Work at the University of Glasgow has already taken a silicon fabricated mass on a spring fabricated using the same Micro- Electro Mechancal System (MEMS) technology to the gyroscope in all smart phones that determine orientation and improved the sensitivity by a factor of 5000\. This MEMS gravimeter has the potential to be used to search for new oil & gas researches, find buried utilities quickly thereby reducing roadworks and provide an early warning for volcanic eruptions. The project aims to deliver a quantum squeezed light source with pairs of correlated photons that can be used to measure the output of the MEMS gravimeter improve the sensitivity by up to a factor of 40\. The project involves developing a photodetector that can detect single photons which also has applications of rangefinding (determining how far away objects are by bouncing photons off them and timing their return) at wavelengths of light that can see through rain, mist and fog.A key objective is to secure a UK supply chain using IQE to deliver commercial Ge on Si epitaxy for single photon detectors and Optocap to produce chip-scale vacuum packages with fibe-optic access which are essential components for the MEMS gravimeter."
