Abstract

A statistical optimum design method suitable for temperature-insensitive waveguide coupler is proposed. Using the method, l2Onm waveband fluorinated polyimide waveguide 3dB coupler is designed with the optimization of the temperature fluctuation. The design result is verified by the 3D-BPM simulation, and shows that the coupling ratio of (50±O.7)% in the waveband of 1490nm ~1610nm and temperature region of -10°C ~40°C is realized. The measuring method for refractive index dependence on temperature and dispersion characteristic of the fluorinated polyimide film is also reported.
