OPTICAL FIBER |
摘要 |
In an optical fiber 1 having a core region 3 and a cladding region 5 which surrounds the core region 3, wherein a plurality of regions made of sub mediums 2 having refractive index different from that of the main medium 4 constituting the cladding region 5 are spaced apart in cross section of the cladding region 5 and the mean refractive index of the core region 3 is lowe r than that of the cladding region 5, the sub-medium regions 2 are regularly arranged in the radial direction of the optical fiber 1 such that the light having given wavelength, propagation coefficient and electric field distribution propagates along the fiber axis and has not less than 50 % of a total propagating power in the core region 3, and this arrangement does not have translational symmetry in cross section.
