Abstract
A method for determining the glass transition temperature T g of waveguiding NLO-films is presented. This enables for the first time monitoring of the Tg of NLO-films on device substrates in situ. T g is shown to follow from the temperature dependencies of the refractive index n(T) or the thickness d f (T) of thin films.Keywords
