Abstract:
A device for amplifying optical signals propagating in optical fibers comprising a double cladding fiber amplifier having multiple gain stages, a port for coupling pump light into the double cladding fiber amplifier, and a double cladding fiber coupler for splitting the coupled pump light between the gain stages of the double cladding fiber amplifier. Also, a method for amplifying optical signals propagating in optical fibers comprising the steps of providing a double cladding fiber amplifier having multiple gain stages, coupling pump light into the double cladding fiber amplifier, and splitting the coupled pump light between the gain stages of the double cladding fiber amplifier.
