摘要： 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.

The thermo-optic coefficients of DR1/PMMA are negative and as high as the order of 10-4/℃.

Key words: thermo-optic effect, polymer thin film
