Abstract
The post-weld-shift (PWS) compensation techniques using a laser displacement meter in TO-Can and a high magnification camera in butterfly type laser-welded laser module packages are demonstrated. These techniques enable to real time quantitatively compensate the PWS induced fiber alignment shift in laser module packages
