Meta-Optics with Mie Resonances

Yuri Kivshar and Andrey Miroshnichenko

Optical magnetic responses and subwavelength localization of light, driven by Mie resonances in high-index nanoparticles, could spur new, breakthrough applications for nanoantennas, nanolasers, highly efficient metasurfaces and ultrafast meta­devices.

Dual-Comb Spectroscopy

Using paired coherent frequency combs for broadband molecular spectroscopy can provide dramatic gains in spectral resolution, sensitivity and data acquisition speed—and may help take the power of frequency comb spectroscopy out of the lab and into the field.

Hello, IRENE: Bringing Old Sounds to Light

Thanks to two optical imaging technologies, long-silent sound recordings of the past will once again resonate for future generations.
