This project aims to develop completely new ways to trap atoms using integrated photonics so the project is looking to pioneer completely new science and technology approaches to cold atoms. Integrating diode laser with photonic cavities and MEMS vacuum chambers will allow the trapping and control of atoms by light. The work is supported by the UK Quantum Technology Programme and the Royal Academy of Engineering. Trapping atoms with light enables atoms to be cooled to below microKelvin temperatures resulting in the most accurate set of sensors that can be used for timing, measuring acceleration, rotation or gravity. Trapped atoms can also form qubits and are also being used to build quantum computers. Such sensors presently require large vacuum chambers with high power lasers to trap atoms with hundreds of Watts of power for operation. This project aims to miniaturize these atom traps using the diode lasers similar to CD/DVD players combined with optical cavities integrated with atoms in MEMS vacuum systems aiming to reduce the size, weight and power to allow these sensors to reduce to the size of a mobile phone and to be powered by batteries.

该项目旨在开发利用集成光子学捕获原子的全新方法，因此该项目正在寻求开创冷原子的全新科学和技术方法。 将二极管激光器与光子腔和 MEMS 真空室集成将允许通过光捕获和控制原子。这项工作得到了英国量子技术计划和皇家工程院的支持。用光捕获原子可以将原子冷却到微开尔文温度以下，从而形成最精确的传感器组，可用于计时、测量加速度、旋转或重力。被捕获的原子也可以形成量子位，也被用来构建量子计算机。目前，此类传感器需要配备高功率激光器的大型真空室来捕获具有数百瓦功率的原子以进行操作。该项目旨在使用类似于 CD/DVD 播放器的二极管激光器以及与 MEMS 真空系统中的原子集成的光学腔来小型化这些原子陷阱，旨在减小尺寸、重量和功率，从而使这些传感器能够减小到手机大小电话并由电池供电。
