VO2 Nanocrystals for Designer Phase-Change Metamaterials
Jimmy John, Yael Gutierrez, Zhen Zhang +5
Subwavelength nanoparticles can support electromagnetic resonances with distinct features depending on their size, shape and nature. For example, electric and magnetic Mie resonanc…

Tailoring the Local Density of Optical States and directionality of light emission by symmetry-breaking
Sébastien Cueff, Matthew Shao Ran Huang, Dongfang Li +4
We present a method to simultaneously engineer the energy-momentum dispersion and the local density of optical states. Using vertical symmetry-breaking in high-contrast gratings, w…

Directional lasing at high oblique angle from metasurface exhibiting multivalley dispersion
Hai Son Nguyen, Florian Dubois, Thierry Deschamps +5
We report on a metasurface laser emitting at the valley extremum of a multivalley energy-momentum dispersion. Such peculiar dispersion shape is obtained by hybridizing high quality…
