Abstract
An electro-optic device includes a substrate structure, a first layer, a second layer on the first layer, and a third layer on the second layer. The first layer includes a first thin film lithium-containing (TFLC) electro-optic material and having a first thickness. The second layer includes a second TFLC electro-optic material and has a second thickness. The third layer includes a third TFLC electro-optic material and having a third thickness. Electro-optic structure(s) of the electro-optic device includes the first layer, the second layer, and the third layer. In the electro-optic structure(s), the first layer has a first width, the second layer has a second width, and the third layer has a third width.
