Pulsed laser welding has proven to be the preferred bonding method that best facilitates the automated fiber alignment and bonding process of optoelectronic devices. However, a combination of considerations regarding (1) the high capita! investment for a laser welding workstation (LWWS), (2) acquiring and developing the packaging technology for laser welding, and (3) the undeveloped demand in the market place have caused hesitation by many manufacturers in adopting the process Typically, the majority of packages manufactured with laser welding have been higher-end priced devices Further understanding and improvement of technical challenges, such as post-weld-shift control, material selection, and package design, along with development of a cost-effective semi-automated LWWS are presenting a greater opportunity for a broader range of packages to be designed for laser welding, especially for low-cost singlemode datacom package-The focus of the current work is to design a broad range of OE packages and develop a nanometer precision automaton process for laser welding technology The solution is recognized to be the combination of understanding the laser welding process, designing packages for laser welding, and developing an automation capability for manufacturing
