Abstract: | We demonstrate theoretically as well as experimentally a new type of four layer polymeric waveguide structure which can be used as mode filter. Various optical properties such as refractive index, birefringence and propagation constant of SAN and K-resin are presented. The thin film structure consisting of glass/K-resin/SAN/air is used to act as mode filter. Expressions for the electric field intensity spatial distribution for the structure are used to calculate the intensity profiles to support the observed behavior. The experimental values were in good agreement with the one obtained theoretically. |
