Programmable Synthetic Motion at a Time-Varying Interface
A. C Harwood, D. Cielecki, T. V. Raziman +3
Space-time metamaterials that exhibit synthetic motion promise arbitrary control over the momentum, frequency and energy of scattered light, but realising the required space-time m…
Competing Auger-Like and Intraband Excitations Drive Anomalous Modulations in Indium Tin Oxide
Anthony C Harwood, Sean Z J Lim, T V Raziman +7
Transparent conducting oxides near their epsilon-near-zero frequency exhibit near-unity ultrafast modulations of the refractive index which have enabled the field of time-varying m…
Optical coherent perfect absorption and amplification in a time-varying medium
Emanuele Galiffi, Anthony C. Harwood, Stefano Vezzoli +3
Time-invariant photonic structures amplify or absorb light based on their intrinsic material gain or loss. The coherent interference of multiple beams in space, e.g., in a resonato…
Space-Time Optical Diffraction from Synthetic Motion
A. C. Harwood, S. Vezzoli, T. V. Raziman +7
The interaction of light with objects and media moving at relativistic and superluminal speeds enables unconventional phenomena such as Fresnel drag, Hawking radiation, and light a…
Minireview on Disordered Optical Metasurfaces
P. Lalanne, A. Dmitriev, C. Rockstuhl +2
The use of coherent wave phenomena to enhance device performance is a cornerstone of modern optics. In juxtaposition to (locally) periodic metasurfaces, their disordered counterpar…
