Abstract

An optical switching device including an optical switching engine may be packaged by omitting an optical bench and disposing optical elements directly on a base of a housing of the optical switching device. The optical switching engine may be disposed on a ceramic portion of the base, and thermally matched to the ceramic base. The base may be reinforced by the housing walls and optional internal rigidity ribs. The optical elements may be thermally matched to the base, and the lid may be strain relieved by thinning lid edges. The housing may be mounted to an external chassis using soft grummets.
