Abstract

PURPOSE: To reduce the driving current resulting in increasing the coupling efficiency and to increase the degree of integration, by taking the constitution that light can be picked up from a pair of surfaces opposed by light emitting elements, and by providing photo detector respectively on two surfaces.
