Abstract

PURPOSE: To improve crosstalk by forming the constitution of a cross section by the 1st clads surrounding the respective cores and the 2nd clads surrounding the 1st clads and satisfying the relations of n(cores)>(clads II)>n(clads I).
CONSTITUTION: The 1st clads 2 of a refractive index (n10 further lower than the refractive index of the 2nd clads 3 of a refractive index (n3) are provided between the 2nd clads 3. If such constitution is assumed, the numerical aperture (NA) of the fibers becomes n(2Δ2)1/2(Δ22=1-n2/n1) and the numerical aperture may be made larger than the numerical aperture (NA)n(2Δ2)1/2(Δ1=1-n3/n1) of the case in which no clads 2 exist. In addition, the providion of the grooves of a refractive index lower than that of the clads 2 makes it possible to accelerate the concentration of light powers into the cores and to decrease the crosstalk due to bending, leacking, imperfection of construction etc.
