摘要:
The invention concerns an optical fiber splicing device (LWL-SPG) for substance-determined connection of optical fibers (F1, F2) by means of an electric corona discharge (GEG). A corona discharge guide (LBF11/12, LBF2, LBF3) is arranged over the electrodes (E1, E2) for the stabilization of the conditions during the splicing process.
摘要:
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.

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.

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.
摘要:
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 fiber coupling unit and optical waveguide arrangement, and method of producing an optical fiber coupling unit. The optical fiber coupling unit 1 has: an optical fiber 2, which has a fiber core 4 and a fiber cladding 6 surrounding the fiber core 4, and a sleeve 8, which is arranged on an end portion of the optical fiber 2 and terminates flush with the associated extreme end 14 of the optical fiber 2, so that on this extreme end 14 there is formed a continuous coupling face 16, with which the optical fiber coupling unit 1 can be placed against an optical waveguide component to establish an optical coupling.
