Abstract
We explore tunable plasmonic metamaterials for electro-optic modulator applications based on ITO-based multilayer structures. Two different structures are investigated, and modulation depth up to 38.8% can be achieved. Preliminary results are presented for the real time response of an ITO/electrolyte gel/doped Si modulator. Furthermore, another modulator configuration is investigated by substituting electrolyte gel by high-k dielectric material (HfO2).
