TRANSVERSAL LOAD INSENSITIVE OPTICAL WAVEGUIDE, AND OPTICAL SENSOR COMPRISING A WAVE GUIDE

摘要

Transversal load insensitive optical waveguide, and optical sensor comprising a wave guide. The present invention is directed to a transversal load insensitive optical waveguide, said waveguide (13) comprising a primary section (17) comprising a core (16), and said waveguide further comprising an outer cladding (18), wherein said primary section (17) comprises a primary section surface (22) and said outer cladding comprises an exterior surface (20) mechanically attached to said primary section surface by means of an interior cladding structure (26) 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, 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.
