Abstract: Electrical tuning of second-order nonlinearity in optical materials is attractive to strengthen and expand the functionalities of nonlinear optical technologies, though its implementation remains elusive. Here, we report the electrically tunable second-order nonlinearity in atomically…

Abstract: In this work, we utilize phase change materials to achieve tunable second harmonic generation from magnetic resonance in bianisotropic plasmonic metamolecules. As a proof-of-concept, we fill the gap of gold split ring resonators (SRRs) with…

Abstract: We experimentally demonstrate the possibility to modulate the second harmonic (SH) power emitted by nonlinear AlGaAs metasurfaces embedded in a liquid crystal (LC) matrix. This result is obtained by changing the relative in-plane orientation between…
