Abstract
Structures that include an optical component, such as a grating coupler, and methods of fabricating a structure that includes an optical component, such as a grating coupler. First and second layers are arranged over the optical component with the first layer arranged between the second layer and the optical component. The first and second layers are each composed of a tunable material having a refractive index that is a function of a bias voltage applied to the first layer and the second layer.
