Methods, systems, and devices are described for electro-optic tuning. An example device may comprise a first layer comprising a transition metal di-chalcogenide material, a second layer comprising a conductive material, and a third layer comprising a dielectric material. The third layer may be disposed at least partially between the first layer and the second layer. An electrical potential difference applied between the first layer and the second layer may cause a tunable refractive index change in the first layer.
