 We can graph the results of the field amplitude in the yz plane by setting diagram 1 with x axis from 0 to the fiber length x: 0, zmax/mm and the y axis from the bottom of the cladding to the top of the cladding y:-r_max/um to +r_max/um. The colors of both the loss and the power are set and information about the transmission can be portrayed on the graph by inserting the incident power transmission function in brackets, for example. The follow code and the graph output are displayed below.

	To model the incident beam profile, we begin by defining the beam size parameter and the normalized super-Gaussian function. The calculation for the beam profile requires a for loop that is quite involved, but a case study on the simulation with the loop can be found on the [https://www.rp-photonics.com/fiberpower_dcf.html RP Photonics software website].

	It is now time to set the grid parameters that will determine the resolution, number of steps, and length of the fiber for the beam propagation. Define the maximum radius to be larger than the cladding to ensure the entire width of the cladding is taken into account. The number of points in the x and y direction of the fiber is taken to be large to ensure sufficient calculation and is set at 2^7. The spatial resolution is defined as the maximum radius divided by the number points in the x and y direction. We take the maximum z to be the total length of the fiber, remembering that the default unit in RP Fiber Power is meters. In our case, we set z_max:= 3000 mm with a longitudinal resolution of dz:=10 mm. The number of steps in the z direction is taken to be the total fiber length divided by the longitudinal resolution. Finally, the number of sub-steps at each dz can be set for further resolution in the z direction. Recognize that the more sub-steps involved for each dz will drastically increase the calculation time of the software.
