Abstract:
An optical device includes a plurality of cores and a clad that surrounds outer circumferential surfaces of the cores and has a lower refractive index than the cores. Each of the cores has a large diameter portion, a tapered portion, and a reduced diameter portion formed along a longitudinal direction and has a refractive index gradually increasing from outer circumference to a center. In each of the cores, a radial-direction distance r (μm) from the center, a refractive index n(r) at the distance r, a relative refractive index difference Δ[%] of the center with respect to the clad, a radius r 0  [μm], and a constant α satisfy predetermined formulas and a wavelength λ [nm] of light propagating through the cores and a diameter R of each core before the diameter reduction with respect to a diameter of each core after the diameter reduction satisfy predetermined formulas.

Claim (Index 1):
An optical device comprising:\n a plurality of cores; and a clad that surrounds outer circumferential surfaces of the cores and has a lower refractive index than the cores, wherein each of the cores has a tapered portion of which a diameter is reduced from one side to the other side of a longitudinal direction and has a refractive index gradually increasing from outer circumference to a center, when r is set to a radial-direction distance (\u03bcm) from the center of the core, n(r) is set to a refractive index of the core at the distance r from the center of the core, \u0394 is set to a relative refractive index difference [%] of the center of the core with respect to the clad, r 0  is set to a radius [\u03bcm] of the core, and a is set to a constant, each core before diameter reduction satisfies the following formulas (1) to (4), and when a wavelength of light propagating through the cores is set to \u03bb [nm] and a diameter of each core before the diameter reduction in the case of setting a diameter of each core after the diameter reduction to 1 is set to R, each core satisfies the following formulas (5) and (6):\n n ( r )=\u0394\u00b7{1\u2212( r/r 0 ) \u2212\u03b1 } (0\u2264 r\u2264r 0 )\u2003\u2003(1) \n 0.9<\u0394<1.2\u2003\u2003(2) \n 22.5< r 0 <27.5\u2003\u2003(3) \n 1.9<\u03b1<2.2\u2003\u2003(4) \n 1530\u2264\u03bb\u22641625\u2003\u2003(5) \n 5581.5/\u03bb< R< 9582.4/\u03bb\u2003\u2003(6).
