In some embodiments, an optical transmission system includes a few-mode fiber that supports at least 2 spatial modes but no more than 50 spatial modes.

Optical transmission using few-mode fibers

In some embodiments, coupled multi-core fiber is used for optical transmission. The coupled multi-core fiber includes multiple cores each supporting a spatial mode. The cores are positioned close enough to cause coupling between their modes that generates supermodes, that are used to transmit data.

Systems and methods for optical transmission using supermodes

Systems and methods are disclosed to perform nonlinear compensation (NLC) in an optical communication system by applying digital backpropagation (DBP) using a frequency-shaped split-step Fourier method (FS-SSFM), and processing a data block using an overlap-and-save method with a block size M and an overlap factor of N samples between adjacent blocks.

Nonlinear compensation using an enhanced backpropagation method with subbanding

Systems and methods for amplification are shown that include a pump preparation module configured to provide a pump output that includes a plurality of pump modes; an amplification module configured to accept a multimode signal input and the pump output, such that the pump output causes an amplification of a plurality of modes in the signal input to produce an amplified signal output; and a gain control module configured to adjust a balance of the plurality of pump modes in the pump output to produce a predetermined amplified signal output.
