Abstract
An optical fiber includes a central core for transmitting and amplifying an optical signal, an optical cladding to confine the optical signal transmitted by the central core, and an outer cladding. The central core is formed of a core matrix and nanoparticles. The nanoparticles are formed of a nanoparticle matrix and rare earth dopants (i.e., a nanoparticle matrix surrounding the rare earth dopants). The optical cladding has a plurality of holes separated by a pitch and extending along the length of the optical fiber.
