Resonance-Enhanced Time Reflection at Photonic Temporal Interfaces
Zeyuan Li, Hammam Bahurmuz, Mohamed H. Mostafa +5
Photonic temporal interfaces enable dynamic control of light fields, yet strong time reflection at optical frequencies remains challenging because conventional approaches demand la…
Multi-mode Photonic Time Crystals Based on Time-Modulated Metasurface Waveguides
Z. Li, M. S. Mirmoosa, V. Asadchy +1
Photonic time crystals are electromagnetic media with periodically time-varying parameters, enabling momentum band gaps, parametric amplification, and frequency conversion beyond w…
Photonic Temporal Illusion
Grigorii Ptitcyn, Diego M. Solís, 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 (PTCs) are characterized by the rapid modulation of the material properties in time, causing a momentum bandgap for light. However, the observation of these…
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…
