Abstract

PURPOSE:To make an optical distributing circuit small-sized and light and to elevate its reliability and productivity, by using only unidimensional platelike focusing optical transmission body, so that it has a distributing function in its inside. CONSTITUTION:A light beam propagated from an optical fiber 101 is wave- guided into a guide area 201 of a platelike focusing optical transmission body 10, is propagated through a mixing area 210, also is distributed to guide areas 201', 202', 203' and 204', is coupled with optical fibers 101', 102', 103' and 104', and is distributed to 4 light beams. In the same way, the light beam propagated from optical fibers 102, 103 and 104 is also coupled with the optical fibers 101', 102', 103' and 104', and is distributed to 4 light beams. On the contrary, the light beam propagated from one of the optical fibers 101', 102', 103' and 104' is also coupled with the optical fibers 101, 102, 104 and 104, and is distributed to 4 light beams.
