Extreme Ultrafast Dynamics of the Refractive Index in Transparent Conductive Oxides: Theory and Experiment
Noa Konforty, Graham G. Brown, Ohad Segal +5
Recent experiments in transparent conductive oxides (TCOs) have revealed light-induced order-unity variations in the refractive index occurring at extreme time scales, as short as…
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…
Pathway to Optical-Cycle Dynamic Photonics: Extreme Electron Temperatures in Transparent Conducting Oxides
Jae Ik Choi, Vahagn Mkhitaryan, Colton Fruhling +4
We theoretically demonstrate that transparent conducting oxides (TCOs) exhibit oscillatory and sign-reversing dynamic modulation in transmittance on the order of a few optical cycl…
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…
