This paper reports the results of studies on polymer waveguides for Integrated Optics (IO). Waveguides were formed using polymers like Araldite, Dobeckot and Epotek epoxy resins, Polystyrene, Polycarbonate and mixture of PMMA and polystyrene. These were characterised using a prism coupler. The selective photopolyrnerisation method was found to be effective in the case of a matrix solution of Epotek epoxy, Methyl acrylite monomer and a photosensitiser. It was found that Araldite PZ-820 can polymerise without the addition of hardener to give films having high refractive index. Such a process was made use of to form fiber waveguides on glass substrates which can be used as optical star couplers and other branching circuits in fiber optic applications.
