Nonlinear Processes in Multi-Quantum-Well Plasmonic Metasurfaces:Electromagnetic Response, Saturation Effects, Limits and Potentials

J. S. Gomez-Diaz, M. Tymchenko, J. Lee +2

Nonlinear metasurfaces based on coupling a locally enhanced plasmonic response to intersubband transitions of n-doped multi-quantum-wells (MQWs) have recently provided second-order…
