Abstract
An optic apparatus includes an optical fiber with a cladding surrounding a core and a core-mode blocker included in at least a portion of an interactive region of the optical fiber. A mode coupler is coupled to the optical fiber and couples a first mode to a different spatial mode in a forward direction of the optical fiber.
