Extreme Nonreciprocity with Spatio-Temporally Modulated Metasurfaces
Andrew E. Cardin, Sinhara R. Silva, Shai. R. Vardeny +7
Emerging photonic functionalities are mostly governed by the fundamental principle of Lorentz reciprocity. Lifting the constraints imposed by this principle could circumvent delete…

Enhanced Second-harmonic Generation Using Nonlinear Metamaterials
Sinhara R Silva, Khagendra Battarai, Alexander Shields +1
We demonstrate a nonlinear metamaterial which enhance higher order harmonics in microwave frequency regime. Nonlinearity in the structure is introduced by adding a varactor diode i…

Tunable Optical Bistability and Optical Switching by Nonlinear Metamaterials
Sinhara R Silva, Alexander D Shields, Jiangfeng Zhou
We demonstrate a nonlinear metamaterial in microwave frequency regime with hysteresis effect and bistable states, which can be utilized as a remotely controllable micro second swit…
