Abstract

PURPOSE: To minimize the deformation of a fusion stretched part by forming the fusion stretched part in a part of plural pieces of the optical fibers formed with ≥1 layers of annular high-refractive index layers having the refractive index higher than the refractive index of the clads on the outer side of the cores of the central part.
CONSTITUTION: Two pieces of the optical fibers 15, each of which is made into a multilayered structure by being formed with the high-refractive index layer 14 having the refractive index higher than the refractive index of the clad 13 on the outer side of the core 12 of the central part, are arrayed in parallel and the fusion stretched part 16 is formed in a part thereof, by which the optical fiber coupler is formed. The power of the mode is withdrawn into the annular high-refractive index layers and the spread of the mode is increased if the annular high-refractive index layers exist on the outer side of the central layers of the cores. The bond between the modes of the respective optical fibers is intensified and the bond between the modes is induced even with a small amt. of stretching. The deformation of the fusion stretched part 16 is lessened.
