Single artificial atoms in silicon emitting at telecom wavelengths
W. Redjem, A. Durand, T. Herzig +15
Given its unrivaled potential of integration and scalability, silicon is likely to become a key platform for large-scale quantum technologies. Individual electron-encoded artificia…
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…
InAs quantum dot in a needlelike tapered InP nanowire: a telecom band single photon source monolithically grown on silicon
Ali Jaffal, Walid Redjem, Philippe Regreny +8
Realizing single photon sources emitting in the telecom band on silicon substrates is essential to reach complementary-metal-oxide-semiconductor (CMOS) compatible devices that secu…
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…
