Abstract
An optical fiber has two or more cores with respective faces on the fiber's ends. The faces are preferably oriented so that optical radiation can be coupled into or out of the individual cores, thereby permitting, for example, optical radiation from the various cores to be spatially resolved in the far field. The faces can be formed on the fiber by polishing the fiber at an angle with respect to the cores, i.e., with respect to the optical paths traversed by the optical radiation passing through the fiber.
