Abstract
Structures for forming an optical feature and methods for forming the optical feature are disclosed. In some embodiments, the structure comprises a patterned layer comprising a pattern corresponding to the optical feature; a base layer; and an intermediate layer bonded to the patterned layer and the base layer.
Claims16
An apparatus comprising:
- a waveguide comprising an optical stack, the optical stack comprising:
- a patterned layer comprising a pattern corresponding to an optical feature, wherein the patterned layer is configured to form a pattern of a waveguide;
- a base layer;
- and
- an intermediate layer bonded to the patterned layer and to the base layer, wherein the optical feature is disposed over the intermediate layer.
