Abstract
An optical communication system comprises a transmitter optically coupled to a single-mode optical channel, and a multimode optical fibre configured to support transmission of a plurality of guided modes. The plurality of guided modes comprises a target mode. The system further comprises an optical mode converter configured to optically couple the mode of the channel to the target mode of the multimode fibre by gradually changing a transverse profile of propagating light received from the channel to match a transverse profile of the target mode of the multimode fibre.
