摘要:
An optical fiber includes a multimode primary core having an index or refraction N.sub.1 and doped with a material providing optical gain; the cladding surrounding the core having an index of refraction N.sub.2 ; and a secondary core doped with an absorbent material for providing optical loss in unwanted modes.
