Abstract: An optical fiber (10) made with a central core (12), a first cladding layer (16), and a second cladding layer (18) having a series of perturbations or irregularities formed into the otherwise generally circular outer boundary of the first cladding layer (16). The irregularities in the first cladding layer (16) interrupt the propagation of skew rays and encourage coupling into the core (12).

Abstract: An optical fiber (10) made with a central core (12), a first cladding layer (16), and a second cladding layer (18) having a series of perturbations or irregularities formed into the otherwise generally circular outer boundary of the first cladding layer (16). The irregularities in the first cladding layer (16) interrupt the propagation of skew rays and encourage coupling into the core (12). An intermediate cladding (14) may be provided between core and first cladding layer (16). A method of fabricatiNG the optical fiber is also disclosed, comprising, drilling a plurality of holes within the first cladding forming material and at the boundary thereof with the material forming the second cladding layer, drilling a central hole and inserting a preform core rod into said central hole. Drawing integrates the rod and drilled rod and the plurality of holes are collaped, so forming an irregular, quasi-circular boundary between first and second cladding forming layers in the drawn fiber.
