Abstract

The solder glass sealing technology is an alternative to the direct sealing method of the socalled hboptocansu. Using solder glass for the junction of glass and the metal can the temperature at about 500 °C does not destroy the optical quality of the precision glass components. The glass can also be coated with an antireflective layer and even the sealing of filterglass is possible. In cases where coupling losses can't be tolerated, the fiber has to be fed directly through the wall into the housing. Fiber feedthroughs, using solder glass for the sealing of the fiber into a metal tube, are commonly metal soldered or welded into the wall and the fiber surface is directly leading to the semiconductor.
