MANUFACTURE OF LIGHTWAVE GUIDE CONSTRUCTION

Light-conducting tracks (3) are produced in a substrate which contains a dopant, at least in a surface layer (2), by heating the substrate in accordance with a preselected pattern. The heating in accordance with a pattern causes the dopant to diffuse out of the substrate at discrete points. The asso...

Beschreibung
Zusammenfassung:	Light-conducting tracks (3) are produced in a substrate which contains a dopant, at least in a surface layer (2), by heating the substrate in accordance with a preselected pattern. The heating in accordance with a pattern causes the dopant to diffuse out of the substrate at discrete points. The associated change in refractive index induces the light-conducting tracks.
