Active Adjustment Techniques

  • Ulrich H. P. Fischer-Hirchert


In this chapter, basic components of active adjustment tools will be introduced. Here, the advantages, disadvantages, and applications of mechanical carriage systems are described for micropositioning and afterward deeply analyzed. Furthermore, an overview of existing possibilities of fiber-chip fixation in regard to the long-term stable welding process is shown. At the end of the chapter an example of the application of microwelds is illustrated and described in detail for the use in modules for optical communications systems. A coupling machine in combination with laser welding performs the fixing of the fiber-chip connection. Hereby, an adjusting welding technique, which is called “strain-reducing” welding, is introduced.
