Abstract:
Metasurfaces, engineered nanostructures designed to manipulate light at scales smaller than its wavelength, have sparked considerable interest for their potential in flat optics applications. Among these are compact spectrometers and spatial light modulators that maintain a low profile. Throughout this presentation, I'll delve into the intriguing features of optical metasurfaces, which empower us to control phase, adjust amplitude, and engineer dispersion, thereby enabling the creation of focusing metalenses and achromatic metasurface devices. Additionally, I'll explore diverse methodologies, such as automatic inverse design, leveraging toroidal resonance modes, and harnessing plasmonic Huygens sources. These approaches contribute significantly to advancing metasurface technology, particularly in the development of high-performance hyperspectral imagers. Finally, I'll highlight a metasurface-integrated microlaser capable of directly modulating light properties at its source.
