Abstract
The out-of-plane elastic modulus, refractive-index, film thickness and birefringence of polystyrene, polymethyl-methacrylate and benzocyclobutane polymer films were determined by means of prism coupling technique. Three dimensional finite element method analysis was used to obtain principal stresses for each polymer and combining them with stress dependent refractive index measurements, the elasto-optic coefficients of the polymer films were determined, for the first time.
