Abstract:
A laser/detector package comprising:an attachment plate having a reference surface; a header post having a front surface that is perpendicular to the reference surface; a spacer having a front surface, a top surface, a bottom surface, and a back surface attached to the front surface of the header post such that the bottom surface of the spacer abuts the reference surface; a sub-mount having a front surface, a bottom surface, and a back surface attached to the front surface of the header post at a position above the spacer such that the bottom surface of the sub-mount abuts the top surface of the spacer, the spacer configured to maintain a precise distance between the reference surface and the sub-mount; and a laser diode attached to the front surface of the sub-mount, said front surface facing away from the reference surface; wherein the spacer and sub-mount are configured to maintain a predefined distance between the laser diode and the reference surface.
