Abstract

PURPOSE:To make possible switching of optical communication paths in the state of photo signals free from leakage by disposing the switching elements each comprising superposing a rectilinear propagation optical circuit and a curved propagation optical circuit with a substrate in-between to an integral unit, in matrix form and turning on and off these by moving means.
