Claim:
1. A multi-core optical fiber, comprising: a plurality of optical cores extending in the multi-core optical fiber along a longitudinal axis of the multi-core optical fiber and comprising a first optical core and at least a second optical core being different from the first optical core; a plurality of cleaves extending from a surface of the multi-core optical fiber into the multi-core optical fiber and comprising a first cleave and at least a second cleave being different from the first cleave; wherein the first cleave comprises a surface, wherein the first optical core ends at the surface of the first cleave, and the surface of the first cleave is configured to deflect the light transmitted in the first optical core such that the light is coupled out of the multi-core optical fiber at the surface of the first cleave; and wherein the at least one second cleave comprises a surface, wherein the at least one second optical core ends at the surface of the at least one second cleave, wherein the surface of the at least one second cleave is configured to deflect the light transmitted in the at least one second optical core such that the light is coupled out of the multi-core optical fiber at the surface of the at least one second cleave, and the first and the at least one second cleave are staggered along the longitudinal axis of the multi-core optical fiber.
