Nonlinearity Reversal in Epsilon-Near-Zero Indium Tin Oxide Driven by Few-Cycle Light Pulse
Mustafa Goksu Ozlu, Colton Fruhling, Ian Hoffman +4
Recent breakthrough studies of nonlinearities at extreme pump intensities (1 ) in transparent conducting oxides (TCOs) have rewritten our understanding of the…
Single-pump hybrid nonlinearities in transparent conductors
Wallace Jaffray, Sven Stengel, Alexandra Boltasseva +7
Low-index transparent conducting oxides have attracted significant attention because ultrafast optical excitation in these materials can induce exceptionally large temporal index g…
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…
Optical Spin Effects Induced by Phase Conjugation at a Space-Time Interface
Carlo Rizza, Alessandra Contestabile, Maria Antonietta Vincenti +5
Electromagnetic temporal boundaries, emerging when the constitutive parameters of a medium undergo abrupt temporal variations, have garnered significant interest for their role in…
Spatio-Temporal Photonic Metalattice
Wallace Jaffray, Sven Stengel, Farhan Ali +9
When coherent light interacts with an ordered lattice whose periodicity is comparable to its wavelength, constructive interference produces a diffraction pattern as in crystallogra…
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…
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…
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…
Engineering Waveguide Nonlinear Effective Length via Low Index Thin Films
Wallace Jaffray, Farhan Ali, Sven Stengel +4
Novel photonic nanowires were fabricated using low-index materials and tested in the near-infrared spectrum to assess their nonlinear optical properties. In this work, we argue the…
Controlling hybrid nonlinearities in transparent conducting oxides via two-colour excitation
M. Clerici, N. Kinsey, C. DeVault +8
Nanophotonics and metamaterials have revolutionised the way we think about optical space (epsilon, mu), enabling us to engineer the refractive index almost at will, to confine ligh…
