For creating flat surfaces along the circumference of a polymer optical fiber of a round cross section by machining, the polymer optical fiber is wound onto a mandrel in a plurality of windings, the mandrel having a generally non-circular cross section with at least one projecting sector in which the radius is constant or, starting from an apex of the largest radius, in which the radius linearly decreases on both sides with an increasing angular distance to the apex, the machining including using a cutting chisel of a high quality for turning-off the polymer optical fiber in the projecting sector of the mandrel. Subsequently, the polymer optical fiber is cut to several pieces that can be used for the manufacture of optical splitters.

Method and apparatus for creating circumferential flat surfaces on round cross section polymer optical fiber

For a precisely fitting alignment of an optical waveguide on an electro-optical component, the electro-optical component is attached onto a submount, which can be attached at any position on a support. For retaining the optical waveguide, a coupling element is selectively provided, the coupling element having a negative imaging of the contour of the submount. This element is positively attached at the submount and receives the end of the optical waveguide. The space between the electro-optical component and the optical waveguide is filled by a transparent adhesive. The submount can be formed in micro-structure technique. The coupling element can be eliminated if the optical waveguide is directly aligned on the submount.

Optical Fiber

A method for producing a microstructured body, in which a casting mold including a casting frame and a bottom plate is formed and is filled with a reaction molding compound. After curing, the casting frame is part of the component, while the bottom plate can be reused. Since both the base plate and the frame have been produced by microstructuring technology methods, this method yields a component that has high precision but can nevertheless be produced inexpensively in large numbers.

Optical waveguide components meeting stringent damping requirements can easily be manufactured with this device.

To planarize an electroformed, magnetic metal sheet having micropatterns, the metal sheet is clamped on a magnet and is mechanically processed on the back side of the metal in such a way that it assumes a plane-parallel shape. Metal sheets can be used which are not stress-free and are obtained in a fast electroplating process. Multiple copying is possible.

In a method for manufacturing an integrated, optical waveguide component having fiber couplings, a substrate component and a cover component are used, the cover component being obtained by forming a positive-negative replica of the substrate component. To separate the optical waveguide pattern region from the regions of the fiber couplings, grooves, as well as corresponding webs, are provided transversely to the fiber couplings. The method eliminates the need for carrying out the fiber adjustment and the waveguide formation in one process.

Method for producing a cover for an integrated optical circuit and cover

A method for producing a hybrid integrated optical circuit which utilizes a molding tool having holding devices for an electrooptic semiconductor component and negative molds for a waveguide trench and holding devices for an optical waveguide. The holding devices of the molding tool adjust the electrooptic semiconductor component with respect to the negative mold of the waveguide trench during reshaping with a polymer. The basic unit produced consists of the electrooptic semiconductor component, which is adjusted with respect to the waveguide trench molded in the polymer. Adjoining the waveguide trench are holding devices, which are molded in the polymer and by means of which an optical waveguide can be coupled to the waveguide trench in a self-adjusting fashion. The basic unit and the optical waveguide are permanently connected to one another with the aid of a cover, the waveguide trench being filled with an optically transparent material, as a result of which a waveguide is formed.
