Effect of dye doping and multilayer structures in polyurethane waveguides

The effect of dye doping and four-layer structuring in polyurethane-based waveguides is presented. The waveguides were fabricated using a dip coating method and characterized by the prism coupling technique. It was found that using these two effects, the various optical parameters of polyurethane wa...

Description
Summary:The effect of dye doping and four-layer structuring in polyurethane-based waveguides is presented. The waveguides were fabricated using a dip coating method and characterized by the prism coupling technique. It was found that using these two effects, the various optical parameters of polyurethane waveguides, e.g. refractive index, birefringence, propagation losses, number of modes, can be suitably controlled. Polyurethane films are highly transparent (above 90%) in the UV-VIS region and this high transparency was found to be present in dye-doped polyurethane films.
