Abstract

PURPOSE: To provide two transmission path outputs whose transmission intensities are not decreased by one transmission part and eliminate the need for switches by applying a modulation voltage to the photo directional coupler of the parallel optical transmission path in which the length of its parallel portion is made OdB coupling length thereby modulating the incident light.
