Polarization-Sensitive Third Harmonic Generation in resonant silicon nitride Metasurfaces for deep-UV Emission
Shroddha Mukhopadhyay, Maria Antonietta Vincenti, Radu Malureanu +3
We present a combined experimental and theoretical study of enhanced third-harmonic generation (THG) in silicon nitride metasurfaces. These structures exhibit strong resonant nonli…
Gold-polymer hybrid metasurface for polarization-independent enhanced third harmonic generation in the ultraviolet
Shroddha Mukhopadhyay, Ana Conde-Rubio, Jose Trull +4
We present a combined experimental and theoretical study of nonlinear light-matter interactions in a three-dimensional gold-polymer hybrid metasurface. In contrast to conventional…
Extreme electrodynamics in time-varying media
M. Scalora, M. A. Vincenti, D. de Ceglia +7
Abrupt time variations of the properties of optical materials have been at the center of intense research efforts in recent years, with the prospect of enabling extreme wave transf…
High-harmonic generation from subwavelength silicon films
K. Hallman, S. Stengel, W. Jaffray +10
Recent years have witnessed significant developments in the study of nonlinear properties of various optical materials at the nanoscale. However, in most cases experimental results…
