| Abstract: | The dispersion characteristics and transverse field distribution of the fundamental and higher-order modes were analyzed for polymer rib optical waveguide by using the finite element method. The effect of the structural parameters on the dispersion characteristics was analyzed, such as the core layer thickness, rib height and rib width. The results show that the rib waveguide will be single-mode transmission when the core layer thickness is less than 1.3 μm, the rib width is less than 5 μm and the rib height is less than 0.2μm. |
