摘要：

Two types of polymer ridge optical waveguide are prepared using new fluorinated polyimides with excellent transparency and refractive index controllability. One has a polyimide core with a refractive index n of 1.573 and an SiO2 undercladding layer. The other has a polyimide core (n = 1.521) and a polyimide undercladding layer (n = 1-520). These waveguides exhibit a low loss of 0.3 dB/cm at 1.3 mum. In addition, they have high thermal stability because of high temperature curing (above 350-degrees-C).
