Abstract
We present a novel image acquisition system to measure the post-weld-shift (PWS) in the butterfly package of a laser diode module. The results show that the measurements of PWS were 1.7 μm and 4.7 μm in the X and Z-axis, respectively. This indicates that the dominant movement of the fiber PWS in a butterfly package is along the Z-axis.
