This is another example of a double-clad fiber amplifier. Different from the above example, we consider all cladding modes and use the built-in mode solution method. According to the refractive index distribution, the numerical aperture of the core, and the conditions of the cladding pumping mode, the mode characteristics are calculated. For simplicity, set the […]
(Note: If passive optical fiber is used, this file and the following case files will not work.) This program helps to learn the basic operation of the software. A simple yttrium-doped fiber amplifier is designed. Both the pump light and the signal light are transmitted in a single-mode fiber. Each wave symbolizes an optical channel. […]

Step index fiber The script program contains a custom table, which is convenient for users to analyze the characteristics of step index fiber. (Friendly custom model) The user inputs fiber parameters such as core diameter, numerical aperture, etc., and can calculate the mode radius, mode field area, and effective refractive index. At the same time, […]
Briefly, the program calculates the distribution of fiber modes by solving the overall model. The script program needs to define the refractive index distribution value. Through several lines of program code, read the refractive index value in turn, and interpolate to draw the refractive index function n_f(r) graph. The following is the related graphics of […]
