  • System and method of packaging a laser/detector
    Patent number: 6577656
    Abstract: The present invention relates generally to laser/detector packages, and particularly to laser/detector packages with components that increase the accuracy and ease of laser diode positioning. In particular, the laser/detector package of the present invention includes an attachment plate having a reference surface; a header post that is perpendicular to the reference surface when attached to the reference surface; sub-mount that houses a laser diode and abuts the reference surface or a spacer, which abuts the reference surface. By abutting the reference surface or the spacer, the laser diode attached to the sub-mount is easily and precisely positioned a proper distance from the reference surface. Additionally, preferred embodiments of the invention include a marking on the sub-mount that is parallel to the reference surface and a marking that is perpendicular to the reference surface on the spacer or sub-mount.
