Apparatus and method for an optical package structure using aluminum nitride

摘要

An apparatus and method are disclosed for providing monolithic optical packages. An embodiment optical package includes a base made of aluminum-nitride (AlN) that is configured to support an optical component, a plurality of sidewalls made of AlN that are coupled to the base, the sidewalls are configured to surround the optical component, and a feed-through made of AlN that is coupled to one of the sidewalls, wherein the feed-through is configured to feed a plurality of leads through the one sidewall to provide an electrical connection to the optical component, wherein the base, the sidewalls, and the feed-through have a same coefficient of thermal expansion (CTE) for AlN. An embodiment method includes punching and printing AlN tapes to build a base, a plurality of sidewalls joined to the base, and a feed-through coupled to the sidewalls, and attaching a plurality of electrical leads into the feed-through.
