ABSTRACT:
Channels in which polymeric optical waveguides can be laid can be milled in surfaces of plastic sheets by means of an excimer laser. The free space between the optical waveguides is filled up with a transparent casting resin.
The channels produced by means of the laser are distinguished by high dimensional accuracy and low surface roughness.
