A guided-mode method for measuring electro-optic coefficients of poled polymer waveguides

A guided-mode method is proposed to determine the electro- optic (EO) coefficients of poled polymer waveguides. This method is based on the measurement of the ordinary and extraordinary refractive indices in poled polymer waveguides by using the prism coupling technique. The relationship between EO coefficients and the change of the index ellipsoid of poled polymer waveguides caused by an applied electric field are derived. The EO coefficients of corona- poled DANS(4-dimethylamino-4'nitro-stilbene) side-chain polymer waveguides are measured by using this method.© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
