Low power nonlinear optical effects in epsilon-near-zero metasurfaces
2020
Nonlinear optical effects provide promising methods of tuning metasurface response. Here we shall demonstrate how Hilbert transforms can be utilized to measure nonlinear dephasing induced by metasurfaces. We further demonstrate that low power thermo-optic effects cause strong dephasing, promising for future design of dynamically tunable metasurfaces.
