Abstract: A package for an optical radiation device comprises a base structure having arranged thereon an optical radiation device, an optically transparent lid element bonded to the base structure defining a cavity between the base structure and the lid element, and a bond structure in a bonding region between the base structure and the lid element, wherein the bond structure is arranged to provide an adhesive bond between the base structure and the lid element, and wherein the bond structure comprises a diffusion layer having a gas diffusive material or gas diffusive structure for providing a gas diffusion path between the cavity and the surrounding atmosphere.
