摘　　要：应用光学布洛赫矢量表示法,研究光在两个弯曲波导之间的相互耦合和能量转换规律,探索不同耦合系数下两个弯曲波导间能量完全转移的机理.结果表明:通过调节耦合波导间的折射率,可以控制两个弯曲波导间的耦合系数,从而实现两个弯曲波导之间的能量完全转移.Based on the representation of optical Bloch vectors,the physical properties of coupling and energy transfer between two curved waveguides is researched and the principle of complete energy transfer of two curved waveguides with different coupling coefficient is explored.The result indicated that the complete power transfer between two curved waveguides could be realized through adjusting the refractive index of coupling waveguides to control the coupling coefficient of two curved waveguides.
