方次律弱导光纤内的束缚场

The bound fields in weakly guiding optical fibre for power-law profiles of arbitrary exponent

在远距离通信中，常用弱导光纤。其传输模式的分析在光纤理论中具有重要意义。文章分析了弱导光纤的束缚场。

The weakly guiding optical fiber is often used in long distance communication.It's important to analyse the transmission mode on fiberoptics theory.The bound fields and cut-off condition in weakly guiding fiber are analysed as well as the bound state numbers as a function of fiber parameters.
