ABSTRACT:
A photonic device package with a passively aligned lens cap is disclosed. The lens cap is positioned with an unobstructed view of the lens portion of the lens cap. A header holding a photonic device, is moved relative to the cap or vice versa until the video display system indicates that the photonic device is aligned to the lens. The cap is held in alignment by forming at least one weld point between the cap and the header. A subsequent hermetic sealing process can be used to permanently seal the cap to the header.
