High-harmonic Generation From A Subwavelength Resonator

Vol48 Issue17 1–5 May 2023

The first observation of enhanced high-harmonic generation has been just reported for a subwavelength isolated dielectric resonator. The first author Dr. Anastasia Zalogina (now at the University of Adelaide) and the last author Dr. Sergey Kruk from Nonlinear Physics Center, said that the ANU technology uses carefully engineered nanoparticles to increase the frequency of light up to seven times, although there is “no limit” as to how high the frequency of light can be generated. The paper has been published in Science Advances.
