Reciprocal Metasurfaces for On-axis Reflective Optical Computing
Ali Momeni, Hamid Rajabalipanah, Mahdi Rahmanzadeh +4
Analog computing has emerged as a promising candidate for real-time and parallel continuous data processing. This paper presents a reciprocal way for realizing asymmetric optical t…
Parallel Optical Computing Based on MIMO Metasurface Processors with Asymmetric Optical Response
Amirhossein Babaee, Ali Momeni, Ali Abdolali +1
We present a polarization-insensitive metasurface processor to perform spatial asymmetric filtering of an incident optical beam, thereby allowing for real-time parallel optical pro…
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…
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…
