Abstract: (3538 Views)
In this paper absorption of pump beam in a fiber with triangular, rectangular, D-shaped and hexagonal inner clad is studied, simulated and compared using two-dimensional ray tracing approach. Obtained results of optimization using Genetic algorithm indicate that the efficiency of pump beam absorption is increased from 68% and 93% for regular hexagonal and d-shaped to 96.7% for non-regular hexagonal geometries.
