聚合物单模光波导的研究

Investigation on a Polymeric Single-mode Optical Waveguide

采用一种间接方法 ,计算出了 DCNP/PEK- c主客掺杂聚合物薄膜在 130 0 nm波长下的折射率 ;在对其平板光波导研究的基础上 ,进行了新型单模倒脊型聚合物光波导的设计与制做。结果表明 ,此种新型光波导具有较好的单模性。

By using an indirect method the refractive index of the guest-host polymer thin film made up of DCNP and polyetherketone (PEK-c) was calculated at the wavelength of 1300 nm. On the basis of the study on polymeric slab optical waveguide, a novel single moded polymeric converse-ridge waveguide was designed and fabricated. The results show that this kind of optical waveguide possesses good single-mode property for practical application.
