有机聚合物热光开关的研究

The optical switch is a key optical component for the modern optical communication systems and networks. Polymer-based optical components have the advantages that its required fabrication technique is simple, its cost is low, its polarization dependence is weak, and it is very easy to realize its low-loss coupling with the standard single-mode fiber. In this project, the large thermo-optic effect of the polymeric material was employed to design optical switches. A 1′2 Y-branch digital optical swotch (DOS) was fabricated successfully while a 2′2 total-internal-reflection (TIR) optical switch was proposed and fabricated for the first time. An invention patent for the TIR optical switch is being applied. The properties of the fabricated samples turned out to be as good as we expected. Through the research work in this project, we not only obtained a certain achievement on the polymer-based thermo-optic switch and related intelligence proprietaries, but also had a lot of valuable experiences and techniques which will benefit our future research and development of more polymeric waveguide components and integrated chips.
