A getter sheet is secured within a package element in a condition of elastic deformation by positioning the getter sheet between a base and a cap of a package with at least one portion of the getter sheet in contact with the package. When positioned within the package, the condition of elastic deformation may force the getter sheet into a vaulted form. Therefore, the getter sheet may be secured within the package without utilizing any additional parts or fasteners. The getter sheet comprises particulates of a getter applied to a sheet of material. The getter sheet may comprise a rectangular shape, an elliptical shape, or an octagonal shape. The getter sheet may be secured within the package when at least one portion of the getter sheet contacts one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base.

The invention claimed is: 1. A package element comprising: a package that includes a base and a cap; and a getter sheet positioned between the base and the cap with at least one portion of the getter sheet in contact with the package to secure the getter sheet within the package in a condition of elastic deformation. 2. The package element of claim 1, further comprising: an electronic device mounted on a top surface of the base within the package. 3. The package element of claim 2, wherein the device comprises an optical sensor. 4. The package element of claim 1, wherein the condition of elastic deformation of the getter sheet forces the getter sheet into a vaulted form within the package. 5. The package element of claim 1, wherein the getter sheet comprises one of a rectangular shape, an elliptical shape, or an octagonal shape. 6. The package element of claim 1, wherein the getter sheet is secured within the package when the at least one portion of the getter sheet contacts one or more of a side surface of the cap, a bottom surface of the cap, or a top surface of the base. 7. The package element of claim 1, wherein the getter sheet is positioned in one of a dome shape, an inverted-dome shape, or an oblique shape between the base and the cap. 8. The package element of claim 1, wherein the getter sheet is secured within the package in a dome shape when two ends of the getter sheet contact a top surface of the base and a side surface of the cap. 9. The package element of claim 1, wherein the getter sheet is secured within the package in an inverted-dome shape when two ends of the getter sheet contact a bottom surface of the cap and a side surface of the cap. 10. The package element of claim 1, wherein the getter sheet is secured within the package in an oblique shape when one end of the getter sheet contacts a bottom surface of the cap and a side surface of the cap and another end of the getter sheet contacts a top surface of the base and the side surface of the cap. 11. The package element of claim 1, wherein the cap includes at least one lug positioned adjacent a side surface of the cap, and wherein the getter sheet is secured within the package when at least one end of the getter sheet contacts the at least one lug. 12. The package element of claim 11, wherein the at least one end of the getter sheet includes a notch, and wherein the getter sheet is secured within the package when the at least one end of the getter sheet that includes the notch clamps onto the at least one lug. 13. The package element of claim 1, wherein the cap includes a lug ring positioned adjacent an entire side surface of the cap, and wherein the getter sheet is secured within the package when at least one end of the getter sheet contacts the lug ring. 14. The package element of claim 1, wherein the base includes at least one slope area, and wherein the getter sheet is secured within the package when at least one end of the getter sheet is inserted between the at least one slope area and a side surface of the cap. 15. The package element of claim 1, wherein the getter includes at least one tab on at least one end of the getter sheet, and wherein the getter sheet is secured within the package when the at least one tab contacts one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base. 16. The package element of claim 1, further comprising: an optical device mounted on a top surface of the base within the package, wherein the cap includes an optical transmission window and the getter sheet includes an aperture to allow light to pass through the optical transmission window and the aperture to the optical device. 17. The package element of claim 16, wherein the optical transmission window substantially covers a light-intake area within the package located on a top surface of the cap outside of the package. 18. The package element of claim 16, wherein said the aperture is substantially centered on the getter sheet and forms an O-shaped getter sheet. 19. The package element of claim 16, wherein the aperture is located at an edge of the getter sheet and forms a U-shaped getter sheet. 20. The package element of claim 1, wherein the getter sheet absorbs gasses within the package. 21. A method comprising: assembling a package with a base and a cap; and securing a getter sheet within the package in a condition of elastic deformation by positioning the getter sheet between the base and the cap with at least one portion of the getter sheet in contact with the package. 22. The method of claim 21, wherein securing the getter sheet comprises positioning the getter sheet with the at least one portion of the getter sheet in contact with one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base. 23. The method of claim 21, wherein positioning the getter sheet comprises positioning the getter sheet in one of a dome shape, an inverted-dome shape, or an oblique shape between the base and the cap. 24. The method of claim 21, wherein the cap includes at least one lug positioned adjacent a side surface of the cap, and wherein securing the getter sheet comprises positioning the getter sheet with at least one end of the getter sheet in contact with the at least one lug. 25. The method of claim 24, wherein the at least one end of the getter sheet includes a notch, and wherein securing the getter sheet comprises clamping the at least one end of the getter sheet that includes the notch onto the at least one lug. 26. The method of claim 21, wherein the cap includes a lug ring positioned adjacent an entire side surface of the cap, and wherein securing the getter sheet comprises positioning the getter sheet with at least one end of the getter sheet in contact with the lug ring. 27. The method of claim 21, wherein the base includes at least one slope area, and wherein securing the getter sheet comprises inserting at least one end of the getter sheet between the at least one slope area and a side surface of the cap. 28. The method of claim 21, wherein the getter includes at least one tab on at least one end of the getter sheet, and wherein securing the getter sheet comprises positioning the getter sheet with the at least one tab in contact with one or more of a side surface of the cap, a bottom surface of the cap, and a top surface of the base. 29. The method of claim 21, further comprising: mounting an optical device on a top surface of the base within the packet; allowing light to pass through an optical transmission window included in the cap into the package; and allowing the light within the package to pass through an aperture included in the getter sheet to the optical device. 30. A package element comprising: means for forming a vacuum enclosure; and means for absorbing gasses within the vacuum enclosure positioned with at least one portion of the means in contact with the vacuum enclosure to secure the means within the vacuum enclosure in a condition of elastic deformation.
