Abstract
An optical subassembly () includes a photonic integrated circuit (), an external optical system () and an optical interface () that is arranged between the PIC and the external optical system. The optical subassembly includes a third material () and a fourth material (). The third material () at least partially fills the optical interface between the PIC and the external optical system in order to minimize contamination of any kind. The fourth material () being in contact at least with the third material for sealing at least the third material from ambient moisture. In this way a low-cost near-hermetic environmental protection barrier () may be provided. An optical system () including the optical subassembly and a method of fabricating such an optical subassembly are also described.
