| Summary: | 碩士 === 國立宜蘭大學 === 電子工程學系碩士班 === 98 === In this thesis, we use the graded refractive index to improve the performance of power division of 2×2 two-mode interfe-rence(TMI) and 2×2 multimode interference(MMI), and the characteristic of wavelength division of TMI and MMI.
The simulation results show that the device length of power divider can be shortened by the graded refractive index. When used in WDM system, we can reduce the structure length of TMI structure and improve the extinction ratio of MMI.
