Abstract
The present disclosure generally pertains to systems and methods for processing optical signals. In some embodiments, an optical system has an optical device for receiving a plurality of optical signals and processing such signals in a desired way. The optical device has one or more functional layers that are separated by buffer layers. The index of refraction of at various points in each functional layer is controlled during manufacturing so that the functional layer performs one or more optical functions or, in other words, manipulates one or more incoming optical signals in a desired way, such as switching, filtering, splitting, focusing, collimating, etc. As an example, the index of refraction profile within a region of a functional layer may be controlled so that an incoming signal from a first optical fiber is redirected for reception by a second optical fiber that is not aligned with the first optical fiber.
