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 5):
The optical device according to  claim 1 , wherein the diameter of the core after the diameter reduction is larger than a diameter of a core of an optical fiber optically connected to the core after the diameter reduction.
