Abstract

Photothermal beam deflection spectroscopy (PTBDS) is used together with waveguide loss measurements to distinguish between intrinsic, absorptive and scattering losses in polymeric waveguide materials. Overtones of vibrational modes of organic waveguide materials in the near infrared spectral regime can be distinguished very precisely with PTBDS. In an example of different polythiophens, we demonstrate the influence of the sidechains (CH_2- and CH₃-vibrations) and the conformation of the mainchain on the absorption spectrum in the spectral regime of optical telecommunications. The photothermal beam deflection method is also used for imaging waveguide structures and to investigate order parameters of dyes within a polymeric matrix.
