Abstract
A method for the attachment and adjustment of a glass fiber end section in which a single monomode glass fiber end section--within a protective housing in the optical active direction of an opto-electronic component (3), such as a GaAs-laser (3) is precisely adjusted and attached toward the optically active area or spot (4) of the laser whereby in a first step, the end section (1) is attached to a support (2) within the protective housing by cementing or soldering and that the axis of the end section (1) is held in the active direction by the support (2) and is provisionally directed at the active spot (4), and subsequently, in a second step, the end section (1) is precisely aligned with the active area or spot (4) through deformation of the support. Prior to the second step or during the first step or prior to the first step, the support (2), which is formed of a solid base (2) of ductile metal such as copper, tin solder or indium solder in a strong, very stiff construction on a common metal block (5) is mechanically coupled with its footing (10) to the laser (3) at a spacing of less than 5 mm from the component (3), and--the base (2) is deformed, through squeezing, in the second step.
