| Abstract: | By the assuming that there is a point optical source at the center of end surface of a fiber,the electromagnetic fields of axis symmetricl guided modes propagating in the half infinite optical fiber are obtained.The frequency properties of the light power of these modes are obtained.The result shows that there is a maximum value of power in cladding for every mode,and that the lower order mode shares the more power. |
