PROBLEM TO BE SOLVED: To provide an optical crossbar. SOLUTION: Plural optical transmission lines 11-1 having wedgelike grooves 110 formed at intervals d2 are arranged on a 1st plane at intervals d1 and plural optical paths 11-2 having wedgelike grooves 110 formed at intervals d1 are arranged on a 2nd plane parallel to the 1st plane at intervals d2 crossing the array direction of the optical transmission lines 11-1 so that the slanting surfaces 112 of the wedgelike grooves 110 face each other between the optical transmission lines 11-1 and 11-2. Each time a light signal 13a transmitted by an optical transmission line 11-1 passes through a groove 110, part of it is reflected downward by the slanting surface 112 of the groove 110 as a light signal 13a. The light signal 13a passes through an LCD provided on the side of the groove 110 of the opposite optical transmission line 11-1 or 11-2 when the LCD is in a light passing state and is transmitted to the groove 110 of the optical transmission line 11-2, and the light has its course changed by the slanting surface 112 of the groove 110 and is transmitted through the optical transmission line 11-2. |
