Raman amplifier with bi-directional pumping
Abstract
An amplifier apparatus Raman multistage, comprising: a first Raman amplifier configured to receive a signal from at least one wavelength traveling in an upward direction in the first Raman amplifier, a first pump source coupled to the first Raman amplifier producing a first pump beam in a downward direction that is contrapropagante respect to the signal; a second pump source coupled to the first Raman amplifier producing a second beam pumping traveling in the upward direction; a second amplifier Raman coupled to the first Raman amplifier and operable to receive the signal from the first Raman amplifier, wherein one of the first Raman amplifier and the second Raman amplifier comprises a Raman distributed amplifier and the other of the first Raman amplifier and the second Raman amplifier comprises a discrete Raman amplifier; and a third pump source coupled to the second Raman amplifier producing a third pump beam traveling in the downstream direction.
