Photonic Temporal Illusion
Grigorii Ptitcyn, Diego M. SolÃs, M. S. Mirmoosa +1
Materials with unusual optical properties are central to advanced control of light. Yet, in nature, such materials may be exceedingly rare and often difficult to obtain. To overcom…
Non-Foster Photonic Time Crystals
Zeyuan Li, Mohammad Sajjad Mirmoosa, Silvio Hrabar +2
Photonic time crystals (PhTCs) are spatially uniform media whose material parameters vary periodically in time, opening momentum bandgaps within which the fields of electromagnetic…
Photonic time crystals assisted by quasi-bound states in the continuum
P. Garg, E. Almpanis, L. Zimmer +8
Photonic time crystals are a class of artificial materials that have only recently been explored. They are characterized by the ultrafast modulation of the material properties in t…
Inverse-designed dispersive time-varying nanostructures
Puneet Garg, Jan David Fischbach, Aristeidis G. Lamprianidis +5
Time-varying nanostructures allow us to control the spatial and temporal properties of light. The temporal modulation of the nanostructures constitutes an additional degree of free…
Broadband amplification of light through adiabatic spatiotemporal modulation
M. H. Mostafa, M. S. Mirmoosa, E. Galiffi +3
Four-dimensional optics leverages the simultaneous control of materials in space and time to manipulate light. A key challenge in experimentally realizing many intriguing phenomena…
Temporal Interface in Dispersive Hyperbolic Media
Grigorii Ptitcyn, Diego Martinez SolÃs, Mohammad Sajjad Mirmoosa +1
Spatial inhomogeneity, temporal modulation, and engineered anisotropy of parameters of electromagnetic media offer numerous opportunities for manipulating light-matter interaction…
