本文从单模单极化(SMSP)光纤中导模与泄漏模的幅度耦合方程出发,推导出耦合功率方程。结果表明功率耦合系数除与两模的传播常数差有关外,还与二者的传输损耗差有关。
In this paper, the coupling power equation is deduced from the amplitude coupling equation of the guided mode and leakage mode in the single mode single polarization (SMSP) fiber. The results show that the power coupling coefficient is related to the difference of propagation loss between the two modes except the propagation constant difference of the two modes.
