The stability of optical clocks, which are based on atoms’ optical transitions, has been demonstrated to be better and they function at a much greater frequency.
The stability and accuracy of optical atomic clocks are more than one hundred times greater than the present microwave atomic clock standard, and they are therefore poised to redefine the System International (SI) second.
The Global Coherent Optical Clocks market accounted for $XX Billion in 2021 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2022 to 2030.
The first high-performance optical cesium atomic clock is called oreSync OSA 3300-HP. The OSA 3300-HP establishes a new standard for accuracy and availability by giving the resilience necessary for PNT assurance and enabling service providers to supply SLA timing options with integrated GNSS backup.
Revision D Si5342H/5344H optical clocks are designed to meet the requirements of coherent optical communications applications.
A standard clock output or a high-speed output (up to 2.75 GHz) can be selected for each low-jitter output (up to 717.5 MHz).
The coherent optical clocks make use of integrated MultiSynth fractional synthesis, third generation DSPLL technology, DCO mode for coherent DSP control through a fast SPI interface, and third generation DSPLL technology to clean recovered clocks.
A project to develop optical atomic clocks to enhance time synchronization has been announced by the US Defense Advanced Research Projects Agency (DARPA).
With less size, weight, and power consumption than atomic clocks based on the Global Positioning System (GPS), the Robust Optical Clock Network (ROCkN) approach attempts to provide clocks with superior timing accuracy and endurance.
