| Abstract: | This paper reports that the thermo-optic coefficient (\dd n / \dd T) as well as
thermal expansion coefficients (\beta) of DR1/PMMA polymer film are measured for
both TE (transversal electric) and TM (transversal magnetic) polarizations by using
an attenuated total reflection configuration at the wavelengths of 832nm. The
thermo-optic coefficients of DR1/PMMA are negative and as high as the order of
10-4/℃. The influences of dopant concentration, poling process and
photobleaching process on the thermo-optic properties of DR1/PMMA are also
investigated. |
