Abstract
A fiber optic modulator of pump energy comprising a piece of double clad fiber where the inner cladding layer has a changing cross sectional shape and may have a changing cross sectional area along the length of the fiber. The modulator fiber regulates how pump energy in the inner cladding layer is absorbed into the core of the fiber along the length of the fiber. This regulates how heat is generated in the fiber due to absorption into core.
