Abstract
PURPOSE: To increase coupling efficiency by reducing the spacing between two elements of light emission and light reception, making the distance therebetween constant, mounting these to one package or ribbon frame and further providing the effect of reflecting the light emitted from surfaces other than light emitting surface on the light receiving surface to the package.
