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…
Analytic Inverse Design of Temporal Metamaterials via Space-Time Duality
Giuseppe Castaldi, Marino Coppolaro, Massimo Moccia +3
Temporal metamaterials, created by modulating the refractive index in time, offer powerful means of controlling wave propagation but still lack a systematic design methodology. Her…
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…
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…
Harnessing the natural resonances of time-varying dispersive interfaces
Carlo Rizza, Maria Antonietta Vincenti, Giuseppe Castaldi +3
Space-time modulation of electromagnetic parameters offers novel exciting possibilities for advanced field manipulations. In this study, we explore wave scattering from a time-vary…
