Abstract
A dual-stage process is implemented to achieve a desired shape degree of flatness and parallelism of a reflective waveguide facet structure. In a first stage, a coarse substrate having two major surfaces opposite each other and a series of facets that approximate a target shape and degree of smoothness is formed. In a second stage, at least one major surface of the coarse substrate is coated with a veneer, and the veneer is shaped using a mold formed by a high-precision tool such as a diamond turned tool to the target shape and flatness of the series of facets. After the veneer is shaped to the desired shape and degree of flatness, the veneer is coated with a reflective coating and the series of facets is embedded in plastic.
