Parametric amplification and bidirectional invisibility in PT-symmetric time-Floquet systems
Theodoros T. Koutserimpas, Andrea Alu, Romain Fleury
Parity-Time (PT) symmetric wave devices, which exploit balanced interactions between material gain and loss, exhibit extraordinary properties, including lasing and flux-conserving…
Non-reciprocal Optical Mirrors Based on Spatio-Temporal Modulation
Romain Fleury, Dimitrios L. Sounas, Andrea Alu
The recent surge of interest in temporal modulation schemes to induce magnet-free non-reciprocity has inspired several exciting opportunities for photonic technology. Here, we inve…
Crystalline metamaterials for topological properties at subwavelength scales
Simon Yves, Romain Fleury, Thomas Berthelot +3
The exciting discovery of topological condensed matter systems has lately triggered a search for their photonic analogs, motivated by the possibility of robust backscattering-immun…
