Strongly Coupled Electro-optic Superlattices and the Potential as Metamaterials
Superlattices consisting of alternatively stacked rhombohedral and tetragonal phases of lead titanate doped lead magnesium niobate were demonstrated. Largely enhanced out-of-plane effectro-optic (EO) coefficient was recorded, which evidences strong spontaneous polarization wave coupling with phonons (structural resonances). This coupling opens up a window to develop new metamaterials having unique permittivity and permeability properties, when using suitable combinations from both ferroeffectric and ferromagnetic materials.
