Tunable unidirectional nonlinear emission from transition-metal-dichalcogenide metasurfaces
Though high-index dielectric metasurfaces are attractive due to their nonlinear effects, channelling of 2nd and 3rd harmonic generation into a single beam remains a challenge. The authors addressed this using transition-metal-dichalcogenide metasurfaces with tunable nonlinear emission direction.
