1. An optical fiber comprising:

  • multiple nonconcentric core regions embedded within a common inner cladding,said core regions sufficiently spaced apart to allow independent operation of said core regions with minimal light interaction,all of said core regions doped with one or more active ionic species andall of said core regions when excited by pump light producing optical gain via stimulated emission of optical radiation propagating within each of said core regions.
