Abstract
An optical coupling system is described incorporating a light emitting semiconductive device mounted on a substrate having an electrically conductive strip leading to and from the device. A plurality of photo detector, semiconductive devices are mounted on the substrate adjacent to and co-planar with the light emitting device. A housing is mounted over the semiconductive devices and is filled with a clear light transmitting resin; the interior surfaces of the housing are light reflecting so that light emitted by the light emitting semiconductive device is reflected and diffused therefrom impinging upon each of the photo detector, semiconductive devices.
