‘Quantum optical antennas’ provide more powerful measurements on the atomic level
From the University of Chicago: Researchers have never been able to tap the potentially huge intensity enhancements of some “atomic antennas” in solid materials simply because they were solids. Now, a multi-institutional team led by the University of Chicago's Alex High has cracked this problem. They have used germanium vacancy centers in diamonds to create an optical energy enhancement of six orders of magnitude, a regime challenging to reach with conventional antenna structures. Read More
