"Every electronic product needs a clock to keep it working and synchronised within the system and nowadays, across the world.Atomic clocks allow the highest possible precision in defining time, which is critical in determining position in navigation and defence systems, and in next generationtelecommunications systems that power the internet age. Atomic clocks are presently bulky and expensive, and the world is demanding ever more timing accuracy. A main cost and size factor comes from the laser and optical systems used inside these next generation of clocks based on a lattice of strontium atoms. The miniaturisation of these systems and their cost reduction is nowrequired to enable entry to a wider commercial market. This project develops special semiconductor laser light sources optimised to enable this miniaturisation and cost reduction. State of the art materials growth at CST Global and chip fabrication at the University of Glasgow is brought together alongside the UKs national measurement institute, NPL to solve these challenges."

“每一个电子产品都需要一个时钟来保持它的工作和系统内的同步，现在，在世界各地。原子钟可以在定义时间时实现最高的精度，这对于导航和防御系统以及为互联网时代提供动力的下一代电信系统的定位至关重要。目前，原子钟体积庞大，价格昂贵，世界对计时精度的要求越来越高。一个主要的成本和尺寸因素来自于这些基于锶原子晶格的下一代时钟内部使用的激光和光学系统。这些系统的智能化和降低成本，现在需要进入更广泛的商业市场。该项目开发了特殊的半导体激光光源，以实现这种小型化和降低成本。CST Global最先进的材料增长和格拉斯哥大学的芯片制造与英国国家测量研究所NPL一起解决这些挑战。"
