文摘This paper reports that the thermo-optic coefficient （dn/dT） as well as thermal expansion coefficients （β） 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.
