📄 原文摘要

Very accurate local clocks play a fundamental role in modern communication and navigation applications. High-precision references enable fast communication data rates, while in navigation they allow longer holdover operation times in the absence of a synchronization signal, for example from the Global Positioning System (GPS). Even if this high accuracy can be achieved with atomic clocks, only the recent developments in photonics and MEMS processes allowed reaching the low power consumptions and small sizes needed for hand-held devices
