Title: OPTICAL FIBER ACTIVE ALIGNMENT USING SUPPORT DEVICE WITH PLASTIC DEFORMATION
Abstract:
An alignment structure (100) maintains an optical fiber in a bore (113). The structure is fixed on a bench and is passively or actively aligned with a light source. Then the structure may be welded or soldered to the optical bench whereby the alignment may suffer due to heat transfer. To correct this, the alignment structure can be plastically deformed to correct the alignment after the components have been fixed. The alignment structure has a substantially constant cross section in a z-axis direction as well as flexible links in order to allow displacements orthogonal to the optical axis. This movements will be initiated by seizing the component with a micro-positioner at a handle (136) and displacing it over the elastic limit to achieve permanent deformation.
