Abstract
A device, system, and method for distributed Raman amplification of a multi-core fiber (MCF) is disclosed. The optical amplifier device includes a plurality of single mode optical pumps configured to supply one or more wavelengths to a depolarizer and a mode multiplexer configured to receive the one or more wavelengths from the depolarizer to output at least one combined depolarized optical light comprising the one or more wavelengths. The device also includes a coupler to couple the at least one combined depolarized optical light into MCF. The combined depolarized optical light Raman amplifies an optical signal in the MCF.
