Abstract:
1. A system comprising: a modulatable source associated with a plurality of source modes to provide a generated signal; and a matched modal filter coupled to the modulatable source to receive the generated signal, wherein a plurality of filter modes associated with the matched modal filter are to match the plurality of source modes to couple the plurality of source modes to the matched modal filter; wherein the matched modal filter is coupleable to a link fiber to provide a signal to the link fiber, wherein the filter modes are to match a subset of link fiber modes associated with the link fiber to couple the plurality of filter modes to the link fiber, and wherein the filter modes comprise at least 4 lowest-order one-dimensional Hermite Gaussian modes corresponding to at least 4 lowest-order one-dimensional Hermite Gaussian modes of the link fiber.
