Broadband, electrically tuneable, third harmonic generation in graphene
G. Soavi, G. Wang, H. Rostami +16
Optical harmonic generation occurs when high intensity light (W/m) interacts with a nonlinear material. Electrical control of the nonlinear optical response enables…
Bright visible light emission from graphene
Young Duck Kim, Hakseong Kim, Yujin Cho +18
Graphene and related two-dimensional materials are promising candidates for atomically thin, flexible, and transparent optoelectronics. In particular, the strong light-matter inter…
Raman spectroscopy of graphene under ultrafast laser excitation
C. Ferrante, A. Virga, L. Benfatto +11
The equilibrium optical phonons of graphene are well characterized in terms of anharmonicity and electron-phonon interactions, however their non-equilibrium properties in the prese…
Large-scale quantum-emitter arrays in atomically thin semiconductors
Carmen Palacios-Berraquero, Dhiren M. Kara, Alejandro R. -P. Montblanch +7
The flourishing field of two-dimensional (2D) nanophotonics has generated much excitement in the quantum technologies community after the identification of quantum emitters (QEs) i…
Raman fingerprints of atomically precise graphene nanoribbons
Ivan A. Verzhbitskiy, Marzio De Corato, Alice Ruini +12
Bottom-up approaches allow the production of ultra-narrow and atomically precise graphene nanoribbons (GNRs), with electronic and optical properties controlled by the specific atom…
Atomically thin quantum light emitting diodes
Carmen Palacios Berraquero, Matteo Barbone, Dhiren M. Kara +9
Transition metal dichalcogenides (TMDs) are optically active layered materials providing potential for fast optoelectronics and on-chip photonics. We demonstrate electrically drive…
