Abstract
A sapphire structure including an ion-implanted, anti-reflective layer and a method of forming an ion-implanted, anti-reflective layer within a sapphire component is disclosed. The method includes forming an ion-implanted layer in a sapphire material at a first depth, and annealing the sapphire material to a second depth. The second depth may be greater than or equal to the first depth. The ion-implanted layer may have a first index of refraction, and the sapphire material may have a second index of refraction different from the first index of refraction.
