Abstract
Fiber optic communications systems are provided that include an optical transmission source that is configured to transmit an optical signal having a first wavelength onto a multi-mode optical transmission path, an optical mode field converter that is optically coupled to the multi-mode optical transmission path, and an optical transmission medium that is optically coupled to the optical mode field converter. The multi-mode optical transmission path has a first cross-sectional area and the optical transmission medium has a second cross-sectional area that is smaller than the first cross-sectional area. The optical transmission medium is a few-mode transmission medium for the optical signal having the first wavelength.
