【Abstract】 The measurements of thermal optical coefficient (TOC) for organic dye doped polymer films using Abbé refractometer was demonstrated;A refractive index contrast necessary for forming waveguide has been achieved easily by adding higher refractive index material to a blank polyer.Based on the measurements of TOC,a novel approach for determining volume thermal expansion coefficient (TEC) of polymer films has been suggested.更多还原
