Abstract
Thin film structures include electro-optic materials and transparent conducting materials which are combined to fabricate vertical optical devices. The electro-optic materials are responsive to an electric field to change an optical characteristic. For example, a modulator can be fabricated by making a dielectric mirror from such materials by alternating the electro-optic material with the transparent conducting material. The mirror reflection band can then be tuned by applying an electric field between the transparent conducting layers.
