Third Harmonic Generation in Transparent Longitudinal Epsilon-Near-Zero Multilayers
Wallace Jaffray, Sven Stengel, Domenico de Ceglia +5
Epsilon near zero (ENZ) materials can dramatically enhance local optical fields, enabling nonlinear interactions at relatively low intensities. Yet, near their plasma frequency, co…
Near-infrared polarimetric imaging with nonlinear flat-optics
Evgenii Menshikov, Marco A. López Sánchez, Paolo Franceschini +4
A compact and broadband polarimetric imaging platform is presented, based on second-harmonic generation (SHG) in nonlinear flat-optics. The system employs periodic all-dielectric A…
All-optical polarization control in time-varying low-index films via plasma symmetry breaking
Wallace Jaffray, Sven Stengel, Alexandra Boltasseva +6
Controlling the polarization state of light with sub-picosecond speed and subwavelength precision remains a key challenge for next-generation nanophotonic devices. Conventional met…
Light structuring via nonlinear total angular momentum addition with flat optics
Evgenii Menshikov, Paolo Franceschini, Kristina Frizyuk +7
Shaping the structure of light with flat optical devices has driven significant advancements in our fundamental understanding of light and light-matter interactions, and enabled a…
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…
