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…
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…
Quantum dots emission enhancement via coupling with an epsilon-near-zero sublayer
S. Stengel, A. B. Solanki, H. Ather +15
Quantum emitters operating at telecom wavelengths are essential for the advancement of quantum technologies, particularly in the development of integrated on-chip devices for quant…
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…
