Ultrafast Third-Harmonic Spectral Modulation and Self-Action in Resonant Nonlocal Metasurfaces
Alfonso Nardi, Sonia Freddi, Michael Scalora +8
Quasi-bound states in the continuum enable exceptional field confinement, strongly reducing the pump intensity threshold for nonlinear light-matter interaction in dielectric metasu…
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…
Unconventional high-harmonic generation in resonant membrane metasurfaces
Pavel Tonkaev, Felix Richter, Ivan Toftul +5
High-harmonic generation (HHG) in solids has rapidly emerged as a promising platform for creating compact attosecond sources and probing ultrafast electron dynamics. Resonant metas…
Spatio-spectral optical fission in time-varying subwavelength layers
Wallace Jaffray, Sven Stengel, Fabio Biancalana +5
Transparent conducting oxides are highly doped semiconductors that exhibit favourable characteristics when compared to metals, including reduced material losses, tuneable electroni…
