Abstract:
1. A dual fiber optic amplifier comprising: a pump source that emits light; a pump splitter that splits the light emitted by the pump source into two or more portions, a first portion directed in a first direction and a second portion directed in a second direction; a first optical power amplifier having an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the first portion of light emitted from the pump source is coupled into the optical fiber input of the first optical power amplifier; and a second optical power amplifier having an optical fiber input, an optical fiber output, and a doped fiber portion, wherein the second portion of light emitted from the pump source is coupled into the optical fiber input of the second optical power amplifier; and a dual path gain equalization filter coupled to both the optical fiber output of the first optical power amplifier and the optical fiber output of the second optical power amplifier.
