Second-Harmonic Generation at a Fourth-Order Exceptional Point Degeneracy
Albert Herrero-Parareda, Domenico de Ceglia, Maria Antonietta Vincenti +3
An anomalous flat-band dispersion provided by a degenerate band edge (DBE) of longitudinal optical modes in a double-grating waveguide is used to enhance second-harmonic generation…
Spatio-Temporal Photonic Metalattice
Wallace Jaffray, Sven Stengel, Farhan Ali +9
When coherent light interacts with an ordered lattice whose periodicity is comparable to its wavelength, constructive interference produces a diffraction pattern as in crystallogra…
Dynamic Control of Nonlinear Emission by Exciton-Photon Coupling in WS2 Metasurfaces
Mudassar Nauman, Domenico de Ceglia, Jingshi Yan +6
Transition metal dichalcogenides (TMDCs) have demonstrated significant potential as versatile quantum materials for light absorption and emission. Their unique properties are prima…
Giant Second Harmonic Generation from 3R-MoS Metasurfaces
Yilin Tang, Hao Qin, Domenico de Ceglia +10
Metasurfaces have long served as a cornerstone technique to enhance nonlinear processes, enabling frequency conversion, efficient light manipulation and integrated photonic devices…
Tunable Unidirectional Nonlinear Emission from Transition-Metal-Dichalcogenide Metasurfaces
Mudassar Nauman, Jingshi Yan, Domenico de Ceglia +6
Nonlinear light sources are central to a myriad of applications, driving a quest for their miniaturisation down to the nanoscale. In this quest, nonlinear metasurfaces hold a great…
Harmonic generation from gold nanolayers: an old problem under a new light
L. Rodríguez-Suné, J. Trull, C. Cojocaru +4
Understanding how light interacts at the nanoscale with metals, semiconductors, or ordinary dielectrics is pivotal if one is to properly engineer nano-antennas, filters and, more g…
