Abstract:
An optical fiber includes: a core; a cladding layer that is lower in refractive index than the core; and a depressed layer that lies between the core and the cladding layer and that is lower in refractive index than the cladding layer, wherein: the optical fiber has an effective core area Aeff that is equal to or greater than 100 μm 2  and equal to or less than 129 μm 2 , the core has a radius r1 that is equal to or greater than 5.2 μm and equal to or less than 7.4 μm, the core has a refractive index volume Vcore that is equal to or greater than 8.5% μm 2  and equal to or less than 16.5% μm 2 , the depressed layer has a refractive index volume Vdep that is equal to or greater than −40% μm 2  and less than 0% μm 2 .

Claim (Index 8):
A method of producing an optical fiber that includes: a core; a cladding layer that is lower in refractive index than the core; and a depressed layer that lies between the core and the cladding layer and that is lower in refractive index than the cladding layer, wherein the optical fiber has a propagation constant difference \u0394\u03b2 equal to or greater than a predetermined value \u0394\u03b20 [rad/m], the method comprising:\n determining a refractive index profile of the optical fiber such that: \n (a) an effective core area Aeff of the optical fiber is equal to or greater than 100 [\u03bcm 2 ] and equal to or less than (16650 [rad/m]\u2212\u0394\u03b20 [rad/m])/63.2 [(rad/m)\u00b7(1/\u03bcm 2 )]; \n (b) a radius r1 of the core is equal to or greater than (9329 [rad/m]+\u0394\u03b20 [rad/m])/3429 [(rad/m)/\u03bcm] and equal to or less than (21180 [rad/m]\u2212\u0394\u03b20 [rad/m])/1714 [(rad/m)/\u03bcm]; \n (c) a refractive index volume Vcore of the core is equal to or greater than (\u2212655 [rad/m]+\u0394\u03b20 [rad/m])/923 [(rad/m)/(% \u03bcm 2 )] and equal to or less than (16420 [rad/m]\u2212\u0394\u03b20 [rad/m])/480 [(rad/m)/(% \u03bcm 2 )]; and \n (d) a refractive index volume Vdep of the depressed layer is equal to or greater than (\u221213300 [rad/m]+\u0394\u03b20 [rad/m])/120 [(rad/m)/(%\u03bcm 2 )] and less than 0 [% \u03bcm 2 ].
