Giant nonlinearity in a superconducting sub-terahertz metamaterial

Giant nonlinearity in a superconducting sub-terahertz metamaterial

We report a superconducting sub-THz metamaterial operating in a CW-regime, which exhibits a record-breaking resonant third-order nonlinearity with effective n2∼10 cm2/W. The nonlinear response is caused by the radiation-induced resistive heating, suppressing the superconductivity in the nano-scale c...
