The invention concerns an optical fiber splicing device (LWL-SPG) for substance-determined connection of optical fibers (F, F) by means of an electric corona discharge (GEG). A corona discharge guide (LBF, LBF, LBF) is arranged over the electrodes (E, E) for the stabilization of the conditions during the splicing process.

Optical waveguide splicer for linking optical fibers in a material fit

The invention relates to an optical chip and to a method for producing an optical chip having a reinforced structure. The chip has a substrate, optical waveguides arranged on the surface of said substrate, and at least one optical structure for influencing the optical properties of the optical waveguides, and an interconnected laminar reinforcing or stiffening structure constructed in the form of a cross which is arranged centrally on the substrate with the provision of diametrically opposite cut-outs.

Optical fiber coupling unit and optical waveguide arrangement, and method of producing an optical fiber coupling unit. The optical fiber coupling unit has: an optical fiber , which has a fiber core and a fiber cladding surrounding the fiber core , and a sleeve , which is arranged on an end portion of the optical fiber and terminates flush with the associated extreme end of the optical fiber , so that on this extreme end there is formed a continuous coupling face , with which the optical fiber coupling unit can be placed against an optical waveguide component to establish an optical coupling.

An optical coupling device for coupling light in between two optical waveguide end faces, in which the geometric position of one optical waveguide end face can be varied with respect to the other optical waveguide end face with the aid of a variable-length element. The element carries one of the two optical waveguides, and is connected to the other optical waveguide via a holding block. The variable-length element is connected to a variable-length compensating element, whose length changes with temperature by the same amount but in the opposite sense as that of the variable-length element. The variable-length compensating element is fixed to the second holding block.

Optical coupling device

A test optical fiber section (F) that resides under tensile stress (F) is heated in at least one longitudinal location so that a constriction (&Dgr;d) of its outside circumference forms thereat. This constriction (&Dgr;d) is acquired and utilized for setting welding parameters.

Method of setting parameters for welding optical waveguides by determining the reduction of a construction diameter

A splice protection device is constructed for acceptance of a pair of light waveguides, with the splice location being optimally sealed by elastic holders having an adhesive film. The elastic splice protection device can be utilized in a bent shape, so that the dimensions of a cassette and other receptacle devices can be designed to be smaller.
