摘要: Waveguide design has always been an important part of photonic integrated devices, and its research is also developing. In this paper, the coupling between waveguides is studied from two aspects of coupled mode theory and finite element simulation. In addition, this paper gives an example of dispersion engineering caused by dual-core waveguides structure, which has a wide range of applications in supercontinuum. To sum up, coupled mode theory has important reference significance for the design of modern photonic devices.
