Similar types of materials could increasingly find use in modern electronics as manufacturers work to make smaller, faster and more energy - efficient components that operate at optical frequencies. (foresight.org)
In addition, in practice the many links in the chain impaired the accuracy of the ultimate optical frequency measurement. (scientificamerican.com)
It is an exciting time, with many laboratories around the world poised to build optical frequency standards that can surpass what has been the primary frequency standard for many decades. (scientificamerican.com)
