Definitions
- the optical fibers can not be bonded directly to one another.
- the holding blocks are attached to the chip, and the optical waveguide fiber is held on the long, variable element.

This Orientie ⁇ tion of the spring portions is in terms of the vibration movements Unterdruk- kung perpendicular to the longitudinal direction of the long verander the element in advantageous.
- a further advantageous embodiment of the device according to the invention is characterized in that the length of the long-variable element is selected such that the spring element is pretensioned in the starting position of the long-variable element. This ensures that the holding device, if it is formed separately from the long-changeable element, follows the long-changeable element when it contracts.
- a further advantageous embodiment of the device according to the invention is characterized in that the two holding blocks are connected to one another by a bracket, the arrangement consisting of the two holding blocks, the long-variable element, the holding device and the spring element being given greater stability.
