treatments is shown in Fig. 13.13, and the insertion loss of PDMS waveguides is
below 0.05 dB/cm after temperature treatment up to 300 °C (soldering conditions).
Further climatic changes had been applied as described in the experimental
section. A similar stability was found for the waveguide loss at 850 nm as described
in Fig. 13.13. According to the identified test conditions, results of the PDMS
waveguide loss measurements at 850 nm are shown in Fig. 13.14. In summary, it
has been proven that the investigated PDMS materials are well compatible with
