Light waveguide arrangement has refractive index inside overlapping region that is greater than in light conducting core regions of light waveguides outside overlapping region

摘要

The arrangement has at least a first and a second light waveguide with first and second light-conducting core regions (1,2) with first and second refractive indices, whereby the first and second core regions have an overlapping region (3). The refractive index inside the overlapping region is greater than in the light conducting core regions of the light waveguides outside the overlapping region.
