Laterally emitting step index fiber for e.g. contour illumination of ship, has scattering zone located between core and jacket, where particles are embedded in zone that includes refractive index differing from refractive index of jacket

摘要

The index fiber has a light guiding core (1) and a transparent and/or translucent jacket (2) made of glass. The core and the jacket include refractive indexes, respectively. A discrete scattering zone (3) located between the core and the jacket is made of glass. Scattering particles are embedded in the scattering zone. The scattering zone includes a refractive index, which differs from the refractive index of the jacket. The particles contain oxides, metals, diamond-like carbon and/or glass ceramic particles. Glass in which scattering centers are embedded is an arsenic-lead silicate glass. An independent claim is also included for a method for producing a laterally emitting step index fiber.
