Anisotropic photonic time interfaces via isotropic spacetime modulations
Andrew M. Naylor, Victor Pacheco-Peña
The engineering of the optical properties of materials in space and time is opening further directions and possibilities to control wave propagation in four dimensions (x,y,z,t). A…

Mirrors without spatial boundaries
J. Enrique Vázquez-Lozano, Victor Pacheco-Peña, Iñigo Liberal
Mirrors are one of the most elementary and ubiquitous components of optical systems. They use a sharp refractive index contrast to provide the basic capability of reflecting light.…

Emulating photonic time interfaces via smooth temporal transitions
Mariya Antyufeyeva, Victor Pacheco-Peña
The introduction of time as an additional degree of freedom to control wave-matter interactions have opened new avenues to fully control wave propagation in four dimensions (x,y,z,…
