Abstract

PURPOSE: To provide construction free from leakage of light by so limiting the mutual relations of the outside diameter of the core of a waveguide, the space of the waveguide, the specific refractive index difference of the waveguide and propagation wavelength region as to be within the specific range.
CONSTITUTION: When the outside diameter of the core of a waveguide is defined as 2aμm, the space of the waveguide as (t)μm, the specific refractive index difference of the waveguide as Δ, and a propagation wavelength region as ≤λμm, these are so arranged that the conditions expressed by aΔ1/2(t/a-2)/λ>1.7 are satisfied. If the above-mentioned parameters are within this range, the selection of the construction that suppresses corsstalk within a range where there are practically no problems becomes feasible in an image fiber. When a transmission system of a visible region (λ=0.4W0.7μm) is considered as an example, the construction free from leakage of light may be provided by satisfying the conditions of aΔ1/2(t/a-2)>1.2.
