Tunable broadband light emission from graphene
Lavinia Ghirardini, Eva A. A. Pogna, Giancarlo Soavi +12
Graphene is an ideal material for integrated nonlinear optics thanks to its strong light-matter interaction and large nonlinear optical susceptibility. Graphene has been used in op…
Temperature dependent moiré trapping of interlayer excitons in MoSe2-WSe2 heterostructures
Fateme Mahdikhanysarvejahany, Daniel N. Meade, Christine Muccianti +12
MoSe2-WSe2 heterostructures host strongly bound interlayer excitons (IXs) which exhibit bright photoluminescence (PL) when the twist-angle is near 0° or 60°. Over the past several…
Position-controlled quantum emitters with reproducible emission wavelength in hexagonal boron nitride
Clarisse Fournier, Alexandre Plaud, Sébastien Roux +9
Single photon emitters (SPEs) in low-dimensional layered materials have recently gained a large interest owing to the auspicious perspectives of integration and extreme miniaturiza…
Highly Confined In-plane Exciton-Polaritons in Monolayer Semiconductors
Itai Epstein, Andre J. Chaves, Daniel A. Rhodes +7
2D materials support unique excitations of quasi-particles that consist of a material excitation and photons called polaritons. Especially interesting are in-plane propagating pola…
Tunable intraband optical conductivity and polarization-dependent epsilon-near-zero behavior in black phosphorus
Souvik Biswas, William S. Whitney, Meir Y. Grajower +5
Black phosphorus (BP) offers considerable promise for infrared and visible photonics. Efficient tuning of the bandgap and higher subbands in BP by modulation of the Fermi level or…
Radially polarized light beams from spin-forbidden dark excitons and trions in monolayer WSe
Sven Borghardt, Jens Sonntag, Jhih-Sian Tu +5
The rich optical properties of transition metal dichalcogenide monolayers (TMD-MLs) render these materials promising candidates for the design of new optoelectronic devices. Despit…
