| Summary: | 碩士 === 義守大學 === 電機工程學系 === 100 === In this paper, we analyze the Grating-Assisted Contra-directional Coupler by Floquet-Bloch theory. We obtain the transmission efficiency and reflection efficiency of grating region and non-grating region by Mahmoud-Beal’s method, and calculate the energy distribution in the grating region. By matching the phase-matching condition, we can obtain the coupling grating period. The simulated results of dispersion relationship and field distribution show the resonance condition. We also successfully simulate the power distribution in the coupler.
