Preparation And Properties Of Fluorinated Polyarylether Polymer Waveguides

In recent years, the development of computer has been severely restricted due to several problems caused by the high speed operation of electrical interconnection. Therefore, optical interconnection network has be gun to enter people’s life. For the transmission of optical information, various types of optical waveguide materials have been extensively studied. As the optical waveguide material, the organic polymer owns the most promising research. The following are its advantages. Firstly, types of materials can be used as optical waveguide materials and they can be integrated with various types of devices. Then the production of optical components is relatively easy and convenient. Because of its high yield and low cost features, we can produce lots of inputs. The refractive index of the waveguide material can be controlled by changing the preparation conditions and it will help us to select the appropriate refractive index for the preparation of optical devices. The last point, transmission loss of the waveguide is low and it can be controlled. This paper mainly uses the method of Spin coating to prepared fluorinated polyarylether waveguide on the quartz glass. The main contents shows as follows:First of all, we introduced the mode of transmission and the testing method of thin waveguide, then we described the preparation of the waveguide sheet in detail.Secondly, this paper used fluorinated polyarylether different main-chain chalcone content as the material to prepare the optical waveguide. We obtained optical waveguide by changing annealing time, annealing temperature and spin coating speed in the preparation process. Finally, we used the method of prism coupling to test the waveguide we obtained. And we compared the data we obtained to get the relationship between the speed of Spin coating and waveguide thickness as well as the relationship between main-chain chalcone content、annealing time and annealing temperature and waveguide performance. Based on the above, when the annealing temperature is at 160 ℃ to 250 ℃ and the annealing time is about 40 min, it can optimize design and then prepare low waveguide loss of fluorinated polyarylether waveguide.
