Abstract
A waveguide, in particular an optical fiber, is coated and is of flexible configuration so that the waveguide can be laid in an adaptable manner, wherein the coating includes a light-frequency-converting substance so that in the event of UV light or IR light being coupled into the waveguide and an overbent waveguide, visible light escapes from the waveguide at a bend point.
Claims18
A waveguide, comprising:
- a core,
- a cladding, and
- a coating, wherein the coating is immediately adjacent to the core,
- wherein the waveguide is of flexible configuration so that the waveguide can be laid in an adaptable manner,
- wherein the coating comprises a light-frequency-converting substance and the light-frequency-converting substance converts UV or IR light into visible light, so that in the event of UV light or IR light being coupled into the waveguide and an overbent waveguide at a bend point, visible light escapes from the waveguide at the bend point, and
- wherein the coating is disposed between the core and the cladding.
A method of identifying a waveguide that is too severely curved, wherein the waveguide comprises a core, a cladding, and a coating, wherein the coating is immediately adjacent to the core, and wherein the coating comprises a light-frequency-converting substance and the light-frequency converting substance converts UV or IR light into visible light, the method comprising:
- laying the waveguide,
- coupling in a UV light and/or an IR light, and
- visually inspecting the waveguide for escaping visible light so that if an escape of visible light is identified at a bend point, the waveguide is too severely curved,
- wherein the coating is disposed between the core and the cladding.
