Abstract
In some implementations, a multi-core fiber amplifier includes a set of fiber cores, wherein the set of fiber cores are arranged within a multi-core fiber, a multi-mode pump laser coupled to the multi-core fiber, wherein the multi-mode pump laser is configured to provide a gain on cores of the multi-core fiber; and a set of out-of-band signal sources coupled to the multi-core fiber, wherein each signal source, of the set of out-of-band signal sources, is coupled to a corresponding core of the multi-core fiber, and wherein a signal source, of the set of out-of-band signal sources, is configured to limit the gain, provided by the multi-mode pump laser, on a corresponding core of the multi-core fiber.
