Abstract
An opto-electronic package having two enclosures in which a first non-hermetic enclosure provides the structural rigidity required to maintain the alignment of the optical components for a predetermined environmental range, and second flexible enclosure that provides a hermetical seal for the opto-electronic package.
Claims20
A package for an optical component, the package comprising:
- a flexible hermetic barrier membrane surrounding the optical component;
- at least one access port hermetically sealed in the flexible hermetic barrier membrane enabling at least one of optical or electrical coupling to the optical component;
- and
- a solid structural package surrounding the optical component;
- wherein the flexible hermetic barrier membrane conforms to the solid structural package, whereby a volume of the flexible hermetic barrier membrane does not change with one or more variations in external environmental air pressure.

A method of manufacturing an optical package, the method comprising:
- mounting an optical component within a flexible hermetic barrier with optical and electrical elements of the optical component aligned with hermetically sealed optical and electrical feedthroughs in the flexible hermetic barrier;
- and
- covering the flexible hermetic barrier with a coating, which hardens into a solid structural package surrounding the flexible hermetic barrier, thereby resulting in the flexible hermetic barrier conforming to the solid structural package and a volume of the flexible hermetic barrier not changing with one or more variations in external environmental air pressure.
A package for an optical component, the package comprising:
- a solid structural package surrounding the optical component with an opening extending therethrough;
- a feed through extending through the opening in the solid structural package, with an access port extending through the feed through enabling at least one of optical or electrical coupling to the optical component;
- and
- a flexible hermetic barrier membrane sheet surrounding the opening, the flexible hermetic barrier membrane sheet having a first seal with the feed through around the access port and a second seal with the solid structural package around the opening and the first seal;
- whereby a volume of the flexible hermetic barrier membrane sheet does not change with one or more variations in external environmental air pressure.
