The demand for data traffic has initiated the development of optical telecommunications. Due to explosive growth of optical network, has brought forward an increased need for guided-wave optical component. The purpose of this work is to investigate the temperature profile in the thermo-optic waveguide. Here, we use one and two dimensional model to analyze the thermal model. We focus on polymer waveguide since these technology is attractive for many advantages, including large thermo-optic coefficient (for Polyurethane (PUR): dn/dt ~ -3.3-4 K-1) and low thermal conductivity ( ~ 0.19 W m-1 K-1). The buried and rib waveguide structure is used for two dimensional model thermal analysis. We interested to see how heating the heater will change the refractive index and change the profile in the waveguide. Thermal coupling became next task of this project. We analyze the effect of heater to the nearby waveguide. To perform this analysis, we utilized a commercial finite element method (FEMLAB 2.0), which is a tool for PDE-based multiphysics modelling in an interactive environment-MATLAB.
