| Abstract(in English) | This paper presents a numerical analysis of bent trench single-mode fibers (TSMF) which have been developed as bend insensitive fibers. The analysis is based on the coupled mode equations between a core mode and a continuum of radiation modes where the radiation modes are represented approximately by a large number of leaky clad modes that include some leaky core modes. The validity of the analytical model was confirmed by applying it to a bent standard single-mode fiber (SSMF). It was clarified that the core mode power varies periodically when it propagates down the bent TSMF due to the coupling with a leaky core mode. The mode coupling grows strong as the bending radius reduces. The leaky core mode exited at the bend may cause a fluctuation in the signal power carried by the core mode by the multiple path interference. |
