Abstract
For many optical communications systems, a semiconductor laser must be situated at an exact position and at an exact distance from a first optical element (for example a lens) of the optical system coupled to the laser. This is achieved according to the invention by arranging the laser in a bushing-shaped cover on which a flange is formed. A holder with a lens is secured on this flange by way of a plastic metal solder layer. The lens can be placed at the correct position and at the correct distance from the laser by sliding and by pressing on the holder. The solder layer is then plastically deformed while the space in which the laser is accommodated remains hermetically sealed.
