Abstract
PURPOSE:To enable the quantity of light to be arbitrarily distributed to a plurality of paths by specifically arranging a plurality of optical fibers. CONSTITUTION:Optical fiber strands 32, 33, 35, 36 each having an almost semicircular end section composed of a circular arc and its chord are fusion-bonded by heating at their ends to form light emergent side optical fiber 31 and light incident side optical fiber 34. The end surface of fibers 31, 34 are then contacted, and by rotating fiber 31 photo signal I1 propagated through strand 32 is arbitrarily distributed to strands 35, 36 as photo signals I2, I3 according to the overlapping degree of core end surface 32a of strand 32 and core end surface 35a of strand 35 or core end surface 36a of strand 36.
