Transversal load insensitive optical waveguide, and optical sensor comprising a wave guide

摘要

A transversal load insensitive optical waveguide includes a primary section having a core. The waveguide may further include an outer cladding. The primary section includes a primary section surface and the outer cladding includes an exterior surface mechanically attached to the primary section surface by an interior cladding structure forming a mechanical connection. The cladding structure is such that for at least part of a distance between each two radial corresponding points on the exterior surface and the primary section surface respectively, the mechanical connection deviates from being radial, so that a radially-directed load on an exterior surface of the outer cladding is deflected by the cladding structure.

1. An optical waveguide, said waveguide comprising a primary section comprising a core, and said waveguide further comprising an outer cladding, wherein said primary section comprises a primary section surface and said outer cladding comprises an exterior surface mechanically attached to said primary section surface by means of an interior cladding structure forming a mechanical connection, and wherein said cladding structure is such that for at least part of a distance between each two radial corresponding points on said exterior surface and said primary section surface respectively a direct connection in a radial direction via the cladding structure is absent, such that said mechanical connection deviates from being radial, for in use deflecting a radial directed load on an exterior surface of said outer cladding by means of said cladding structure.
