Abstract

PURPOSE:To obtain the branching device of simple construction and easy adjustment by opposedly disposing one single-core optical fiber and the multifibers which consist of multiple single-core optical fibers and in which the central single-core optical fiver is deviated to the inner side. CONSTITUTION:One single-core optical fiber 31 and the multifibers constituted by multiple optical fibers 32, 33... which branch and transmit the transmitted light from said single-core optical fiber 31 are opposedly disposed. the intensity distribution of the transmitted light of the single-core optical fiber 31 assumes the distribution in which the central part is strong and the peripheral part is weak and its angles theta spread at a fixed ratio. Because of this, the intensity distribution of light becomes light A at the exit face and becomes like C at the distance l2 from the exit face. Hence, by deviating the optical fiber 33 occupying the central position among the multiple optical fibers to the inner side, the transmitted light may be evenly entered to each glass fiber constituting the multifibers. In this way, the branching device of simple construction and easy adjustment may be obtained.
