Abstract
A tunable optical device includes a thin film device. The thin film device includes a plurality of cavities each including an electro-optic material. The electro-optic material includes an optical characteristic capable of being manipulated by application of an electric field. In this embodiment, at least some of the plurality of cavities are coherently coupled to others of the plurality of cavities. In this embodiment, the plurality of cavities include a sufficient number of cavities to result in an approximately square frequency response for the device.
