Electro-optical modulation of light polarization in a nonlocal lithium niobate metasurface
Agostino Di Francescantonio, Alessandra Sabatti, Eleni Prountzou +6
We report the experimental realization of a LiNbO3 metasurface for electro-optic modulation of light polarization in the telecommunication band. High-Q quasi-bound states in the co…
Tensor-driven geometric phase in nonlinear AlGaAs metasurfaces
Giorgio Guercio, Andrea Gerini, Kristina Frizyuk +5
Dielectric metasurfaces provide a unique platform for efficient harmonic generation and optical wavefront manipulation at the nanoscale. While several approaches are available for…
Nonlinear Nonlocal Metasurface for Harmonic Generation and Manipulation
Hooman Barati Sedeh, Yuruo Zheng, Jiaren Tan +7
The discovery of second harmonic generation in 1961 marked the birth of nonlinear optics, unlocking a range of applications from frequency conversion to quantum light generation. Y…
Chiral high-harmonic generation in metasurfaces
Piyush Jangid, Maria Antonietta Vincenti, Luca Carletti +3
High-harmonic generation (HHG) provides the only source of attosecond pulses -- currently the shortest accessible time intervals, and it is employed as the only table-top source of…
Efficient GHz electro-optical modulation with a nonlocal lithium niobate metasurface in the linear and nonlinear regime
Agostino Di Francescantonio, Alessandra Sabatti, Helena Weigand +8
Electro-optical modulation is widely employed for optical signal processing and in laser technology. To date, it is efficiently realized in integrated photonic systems as well as i…
