Abstract

Abstract: A novel material fluorinated hyper branched polyimide(FHBPI) was synthesized for using in thermo-optic waveguide switch applications. This material has high thermal stability. Differential scanning calorimeter(DSC) and thermo-gravimetric analysis(TGA) were taken to evaluate the glass transition temperature(T_g) and the thermal decomposition temperature(T_d,5%). The results indicate that T_g and T_d,5% are 189 and 596 ℃, respectively. The film quality of FHBPI is excellent. The atomic force microscopy(AFM) exhibits the surface roughness of FHBPI film, which is 0.54 nm. FHBPI has a high optical transparency in the infrared communication region. The thermo-optic switch device was designed, fabricated and tested by FHBPI. The rise time and fall time of the switch are 267.9 and 254.1 μs, respectively.
